Need clear turn and parking lights that stand out day or night? This oval incandescent trailer light handles both jobs with a bright amber lens that easily catches attention. It uses a standard 12V DC setup and draws 2.4 amps for the turn signal and 0.50 amps for the tail light. The 6-1/2" long by 2-1/4" tall housing keeps it compact while giving plenty of light output to mark your trailer clearly.
If your trailer sees rain, spray, or boat launches, this light is ready for it. The polycarbonate lens and housing are sealed together to make it waterproof and submersible. Inside, a shockproof socket protects the bulb from bumps or vibration so you can count on it staying lit even after long hauls or rough terrain.
Getting a smooth, factory-style finish is easy with this recessed-mount light. It installs in a cutout using a rubber grommet (A70GB – sold separately) for a snug, flush fit against the trailer body. If you’d rather not cut a hole, an optional mounting bracket (BK70BB – sold separately) lets you surface-mount it neatly instead.
No custom wiring needed here. The light connects with a standard PL-3 three-prong plug that works with right-angle or straight pigtails (A47PB or A45PB – sold separately). Just plug in, wire by function, and you’re ready to go with reliable power and grounding every time you hook up the trailer.

Everything I order from etrailer ships quickly and performs as it should. Great service! Roy
I bought these to replace the sealed units in my tow master tow dolly. they are 1/16" thinner than the originals but fit and work exactly as the originals once did. hooked up the same using existing connections also.
Good product at a fair price. Just what I was looking for. Quick shipping.
Exactly what I was looking to get for my tow dolly. Fast shipping--items worked perfectly! Would highly recommend! Thanks!
I needed 5 different kinds of lights for my boat trailer since they had all burnt out. Etrailer had all of them in stock. They were shipped out the same day I made the call. Three days later they were delivered. Steve Z helped out a lot with my phone order. They get 5 stars from me!!

Thanks for the fast service and great prices! Works great!
I received the Oval Trailer Turn Signal and Parking Light-Amber- ST70AB in good condition. I haven't had time to install it on my trailer but I'm sure that it will work when I do have the time. Thanks for the fast shipping and the correct item.
Items were exactly as described and the Adapter and oval trailer light (amber). I accidentally ordered the wrong size Trailer wheel center caps (ordered 15" and I needed 14") the staff (Madison) was very helpful and friendly and walked me through the exchange process. Love doing business with etrailer.
Could not find the amber light on line so had to for assistance
Associate was knowledgeable
Took the order
Parts arrived sooner than scheduled and were a direct fit
Good job

Lights are working great, no problems, I trailer my boat allot, backing in and out of water without disconnecting the light harness and have no problems, well satisfied

Great! Ordered all lights for my 15 year old boat trailer. Quick shipping. etrailer had everything in stock as usual. Can depend on etrailer for all trailer parts.
im actually disappointed. the first one i put in filled up with water and burned up the first time i backed in the boat. i took off and seen it was cracked, had to have been manufacturing as i only live 2 miles from the ramp. and now the 2nd one has already went out. i guess i'll spend more money to replace the 2 flawed trailer lights. the original was 7 years old, now i've went through 2 of yours.
The amber lights are of poor quality. I have red, amber, and white lights on my boat trailer in various places (side, reverse, back/break lights). I replaced both amber lights because the went bad. The amber lights have both blow out...again. These are the only lights that have burned out on my 5 year old boat trailer.
Exactly what I was looking for. I have four of these lights on my Dart trailer, two red and two amber. One went out in the middle of a trip last year and it was a couple of days before I found a replacement at a truck stop. Now I'm prepared for the next time.
I replace these lights on my master-tow trailer constantly. The filaments just can't tolerate the lack of suspension on the trailer when it's empty and they blow out.
No issues with the light other than that. I would recommend investing in the LED replacements rather than these.

Hello Ryan - the ST75AB lights do come with shock mounted bulbs, but excessive vibration with a lack of suspension could definitely cause problems. I would suggest moving to the STL75AB LED version. Optronics offers a LIFETIME LED Warranty, so you shouldnt see any problems no matter what type of vibration your trailers endures.
My husand has installed an aluminum flat bed on our pickup truck to replace the original rusted out one. He used the amber turn signal/ parking light to replace the red lights that came with the flat bed. The lights were a perfect fit and are just what we needed.

The trailer lights have spent time out in the rain, snow and 90 degree temperatures and are still looking and working great.
Great replacement for my trailer! Thank you!
The Lights were easy to install and work great and shipping was on time.
