My etrailer products I have ordered have and continue to be good products at reasonable pricing. I look forward to doing business with etrailer again as I am sure I will have a need for more items.

Speedy delivery - they arrived before I've been able to use them - so my 4 star rating is reflective of this review being incomplete. All products in my order look to be intact and in new condition so I expect they will work well when I finally get around to mounting them on my utility trailer.

Perfect fit. Good product description so felt confident ordering on internet.

Products exactly as ordered. Very fast shipping. After I ordered, I realized there was another item I wanted. I called the 800 number and Steffen was a great help, cancelled the current order, placed everything in a new order and added the new item I wanted. Allowed me to get the savings due to order value. Great service.

  • Replacement Light Bulbs for 2008 Forest River Flagstaff MAC 228
    We do have the Replacement Light Bulb # 1157 # A1157B that you're looking for, but we do not have a C193 incandescent bulb available at this time. If you wanted to replace it with an LED light, the Starlights LED Wedge Base Lamp # 277-000102 can be used to replace the 193 or the 194 light bulb, among others.

  • Replacing the Bulb on a Wesbar Light with a Clear Capsule
    Good news, the clear protector can be removed to replace the bulb. There are two styles of capsules for these lights, one you can replace the entire capsule and the other holds the capsule lid on with 4 Phillips head screws. You won't have to worry, because both applications allow you to remove the cap and replace the bulb. If you are looking for a replacement bulb the # A1157B will be the one for this light. I linked a video that better shows the inside of the light and the capsule...

  • Available High-Efficiency LED-Type Lights to Replace Halogen Type Bulb
    Most of the RV kitchen range hood vents we offer come with incandescent bulbs as standard. For many such bulb types we do offer LED equivalents. For instance, for an 1157 type incandescent bulb like # A1157B you can use an LED replacement like # CM93236. The linked page displays all LED replacement light parts. One you find your bulb number you can click on that filter to then see suitable LED options.

  • Can 1157 Light Bulbs Be Used on Boat Trailer
    As long as the existing light housings on your boat trailer are compatible with 1157 bulbs # A1157B, they will work just as well as a 2057 bulb. One light that the 1157 bulb is designed as a replacement for and that will work well on a boat trailer is the Wesbar Submersible Low Profile Trailer Tail Light, Left Side # 403026 and Right Side # 403076.

  • Comparing Optronics Replacement Trailer Light Bulbs 1157 and 2057
    The Optronics replacement bulb, # A1157B and bulb # 30-84-057 are dual filament bulbs. The double-filament design works for combination brake, tail and turn lights. A 2057 can replace an 1157 bulb.

  • Why Does the Replacement Bulb # A1157B Illuminate Bright or Dim Depending on Orientation
    The # A1157B that you referenced is a dual intensity bulb. Depending on which circuit you connect to on the light you could illuminate either the low or high intensity. What I would recommend you do is activate the running lights of the trailer you are installing this bulb into and then install this bulb in the orientation activates the dimmer illumination. Then check to make sure it gets brighter when the brakes are applied.

  • How to Remove and Install 1157 Bulb From Trailer Lights
    For an 1157 bulb like the # A1157B, in order to remove the old one you'll want to gently push down on the bulb while twisting the bulb 1/4 turn counterclockwise. You should then be able to pull the bulb from the socket. When replacing the bulb, align the dual notches on the base of the replacement bulb to the grooves inside the socket.

  • How to Identify Correct Replacement Bulb for RV Porch Light
    If you can find a bulb number on your porch light's original bulb we may not need you to submit a photo. Most smaller incandescent bulbs will have a number printed right on the bulb glass or stamped into the metal base, such as on part # A1157B, which is an 1157 type bulb. If you can find a bulb number simply enter that into our search box to see replacement parts. Depending on the bulb required we may be able to offer you an LED equivalent that will produce less heat and use only about...

  • Tail Light on Trailer Not Working After Installing New Bulb
    If all of the other lights on your trailer are working correctly except the new 1157 bulb that you installed, like part # A1157B, then either the wiring to your light housing is bad, or the housing itself is bad. Check the wiring for the housing to make sure that it is not corroded, bent, damaged, or exposed, and also make sure that the ground is securely connected to a clean, bare metal surface. If all of that looks good then the housing is probably bad and needs to be replaced. I...

  • Troubleshooting 1157 Replacement Light Bulb That Will Not Illuminate
    An 1157 bulb like # A1157B installs by rotating it in the socket so that the two small tabs on its base lock into place. This makes the ground connection. The bottom of the bulb's base has a contact for the +12V input. Please check that the bulb is fully inserted and rotated into its locked position. If you see any discoloration at all on the socket - even slight greenish or whitish discoloration - this can indicate corrosion that could be interfering with power reaching the bulb. You...

  • Which Filament in Optronics Bulb # A1157B is Used for the Turn Signal
    The Optronics 1157 Replacement Bulb, part # A1157B, and similar dual-filament bulbs such as # 30-84-057, have two different filaments. One filament is of a different resistance value, and thus makes a brighter light. That is why one bayonet on the bulb casing is at a different position than the other bayonet - so that you dont install the bulb the wrong way. The basic filament usually on the brown wire is running lights, the other filament usually green or yellow depending on which side...

  • What are the Correct Replacement Bulbs for Optronics Trailer Lights # ST6RB and # ST7RB
    It looks like you have Optronics Lights # ST6RB and # ST7RB. For either of these lights, the correct replacement bulb will be # A1157B that you have referenced and # 30-90-194 for the side light. Trailer lights are a 2-wire system. This means that they have combined stop and turn signals on the same bulb. If the lights do not blink with the turn signals, you may need to change the running light wire with the stop/turn signal wires. Use a circuit tester like # 40376 to test the trailer...

  • Can 1141 LED Bulb Replace 93 Incandescent
    93 bulbs and 1141 are compatible replacements for each other so if you have a 93 you could use the part # AR50367 for a soft white LED replacement.

  • What Causes Light Activation Delay on RV
    Typically light activation delay is due to a bad switch or a loose connection in the wiring of the light circuit. It's not usually related to the wrong bulb being used. I'd first check the condition of the switch looking for any corrosion and then check the wiring.

  • Replacement Bulb for Wesbar Low Profile Trailer Tail Lights 403026 and 403076
    It sounds like you're looking for the replacement bulbs only for the Wesbar Low Profile Trailer Tail Lights # 403076 and # 403026. The replacement bulbs for these lights are the Replacement Light Bulb 1157 # A1157B.

    The Wesbar trailer taillight like part # 43026 uses a 1157 bulb like the # A1157B for an incandescent or # P231157R360 for an LED. LEDs are much brighter, last longer, and draw considerably less than incandescents.

  • How to Change Light Bulb in Optronics ST8RB Trailer Taillight
    Changing the bulb is simple. Remove the screw on each corner of the front of the lens and gently pry the lens away from the housing. Be careful not to damage the gasket between the lens and the housing as doing so will allow water into the interior of the lamp. With the lens removed, you can push in on the bulb and twist it clockwise then pull the bulb free. Install the replacement # A1157B bulb in reverse order..

  • Troubleshooting Tail Light Bulbs After Replacement
    The incandescent bulb type 2057, part # 30-84-057, is a double-filament type that handles multiple functions and so is the 1157 bulb, part # A1157B. But all replacement bulbs are best selected using the bulb number from the original part. We even have a red LED version of the 1157, part # P231157R360. If your new bulb is not functioning you can test the socket using a circuit tester like # PTW2992 to see if power is reaching the socket. Use of the tester is demonstrated in the linked...

  • Are the Bulbs or Just the Capsule Replaceable in the Wesbar Trailer Tail Light # 106411
    I went out to the warehouse and pulled a Wesbar trailer light, # 106411, to examine it more closely. After taking it apart I found that you can replace just the bulbs inside the capsule. The same goes for # 106410. The larger bulb is an 1157 bulb, # A1157B, and there can also be a smaller bulb labeled as C193. I made a short video showing the light taken apart for you.

  • Changing the Bulb in the Wesbar Tail Light Capsule
    The older generations of the Wesbar submersible low-profile lights came with sealed light bulb capsules that are not replaceable. If your capsule is sealed, then your best option is to replace the lights with new lights like part # 403026 and # 403076. The new lights come with capsules that allow you to replace the bulbs. The bulbs used in these lights are # A1157B and # 193.

  • Availability of Replacement Capsules for Wesbar Trailer Lights
    Some Wesbar lights have a the sealed type of capsule, and they are not meant to be opened. Instead, you would need to replace the whole capsule. The good news is that Wesbar offers replacements, depending on the model number, that can be easily opened to change worn parts, in addition to the sealed type. If you have a Wesbar Submersible Low Profile Light # 403026 and/or # 403076, the bulbs can be replaced by removing the clear capsule inside the light. If you want to swap it out for...

    I first recommend testing the 4-Way connector on your F-150 without the Pilot Light-Up Rectangular Trailer Hitch Receiver Cover # CR-007XL connected. You can test each function on the connector with a circuit tester like # PTW2993. Check to make sure you are receiving power at the appropriate pins while a buddy sits in the vehicle and activates each function. If everything checks out okay, I also recommend verifying that the white wire on the vehicle side connector is grounded firmly...

    The Wesbar Trailer replacement tail light lens, part # 102641, which you referenced, fits over 80" red rectangular tail lights # 403076 and # 403026. These lights take light bulb # A1157B, which uses 8.3 watts for tail light function and 26.9 watts for the stop/turn function.

  • How to Change Tail Light Bulbs in a Submersible Trailer Tail Light
    If you have a newer model Wesbar Submersible Low Profile Trailer Tail Light, item # 403076, there are screws on the inside of the housing securing the clear capsule to the light housing. Removing these screws will allow you to remove the clear capsule cover and replace the bulbs. When the clear capsule is replaced an o-ring seals the bulb. The replacement bulb is part # A1157B. The older Wesbar tail lights used factory sealed capsules to prevent water from getting to the bulb and socket....

This light takes a 1157 bulb like the # A1157B for an incandescent bulb. The side clearance lights appear to be the part # MC31RB for red and # MC31AB which use 194 bulbs like the # A194B.
