Good lighting makes all the difference when you’re out on the road. This Peterson Double Bullseye clearance and side marker light uses two 194 incandescent bulbs to throw out bright, even light through its red acrylic lens. Each premium bulb delivers up to 15,000 hours of life, giving you consistent visibility with minimal upkeep. With a total power draw of only 0.25 amps at 12V, it’s efficient while still cutting through the dark when visibility matters most.
No complex wiring here. The single-wire design powers the light while grounding through the mounting hardware, making installation clean and straightforward. It mounts on standard 3" centers with a surface-mount layout, so it sits flush without extra brackets or drilling for the wiring. It’s a simple setup that keeps things tidy and dependable once installed.
Seeing and being seen from every angle is key for safety. This light’s PC rating means it produces a 90-degree beam from either side of its centerline for a full 180 degrees of coverage. When properly mounted, it works as both a clearance and side marker light, so drivers can spot you from the front or side—ideal for staying visible in low-light or busy traffic conditions.
The sturdy rectangular housing measures 4" long by 2" tall and 1-1/8" thick and stands up well to everyday use. Its snap-on acrylic lens makes bulb changes quick while keeping moisture and debris away from the sockets. DOT compliance ensures it meets lighting standards for road use, so you can trust it to perform mile after mile without fuss.

Great replacement lights
Always count on ETrailer to have everything you need.
Used etrailer.com a lot - big or small parts every time they deliver!
The product came as specified and out of 5 replacements, all were consistently in tact, fully functioning, and fit perfectly on my 1980 Airstream Caravelle.
The trailer lights are great, they're great quality and were a great replacement for the old lights of my Grumman Olson
I got my order delivered when it was supposed to be here. Everything came without anything damaged. The only complaint was that the packaging was loose, I was surprised that the side marker lights survived the ride.
As described with a lead for your chased activation energy and but grounds to trailer. Make sure you have this scenario and these lights will work perfect!
Fit nice. Work great.
Quality product. Still shining bright.
Great replacement lights
The trailer lights are great, they're great quality and were a great replacement for the old lights of my Grumman Olson
Got this as a replacement for one damaged on our '95 Airstream. Easy to install, looks great with the older originals. Price was much better than getting OE.
Perfect fit, great price, fast easy delivery. What else could you ask for. eTrailer has outstanding customer service as well.
As described with a lead for the positive activation energy and grounds to trailer. Make sure you have this scenario and these lights will work perfect!
Excellent 1-wire clearance lights. Good price, too.
These lights lined up with the mounting posts on a 89 Tioga class-c motorhome, perfectly.
These lights have two bulbs, and ground off the post. On my 89 ford tioga, the rear clearance lights were ground on one post and hot on the other. I had to modify these clearance lights to ground on only one post and used a ring connector on the 1-wire, connected to the hot post. On a couple of the lights I had to solder a jumper wire on the aluminum ground strip so that both bulbs would be grounded off of one post. You'll know what I mean when you look at the light.
Otherwise, great product.
I used this light in red and amber to replace the clearance lights on my 1970 Airstream. I thought it would be a close match to the 45 year old crumbling lights on my trailer. As it turned out, the lights were nearly an exact match to my originals, even the mounting holes lined up. However the hole in the back for the wire did not line up. I had to enlarge the hole for the wire to pass through. I used pop rivets to attach the base to the trailer and each light worked perfectly. The center light in the picture is the new one.
Ordering was simple and shipping was fa st!
