led taillight replace

The one that would be the 1157 replacement.

why not replace the entire light with an LED fixture ?

There is no real good reason changing out the trailer safety lights if you are trying to save DC Power on your trailer batteries. The Trailer safety lights run off of the truck start battery system not the trailer batteries...

These safety lights are DOT approved when the trailer folks built the trailer. The LED replacement bulbs/boards for the 1157 automotive bulbs may not be DOT approved to use for the trailer tail light assemblies. Using replacement LED lights for trailer safety lights may have to use a complete DOT LED Lamp assembly...

Since these lights are powered by the 12VDC truck start battery system you will not gain any useful trailer installed battery DC Power savings wise.

Something to check with DOT/DMV about at any rate...

Just my thoughts here...

why bother. I think I have replaced one or two tail light bulbs the last 50 years.

We replaced the entire tail-turn light fixtures on the rear of our motorhome with LED fixtures and the increase in daytime visibility was really pronounced. If you can find the direct LED fixture replacement, it's pretty much plug 'n' play. Even I could do it. :)

I replaced my taillights with LED fixtures. It wasn't a "save power" thing for me it was visibility.
The ones I bought from Amazon were only $42 and pretty easy to install.

I thought the tail light / brake lights, were just not bright enough to catch drivers attention on my 2006 30' Wildcat.

So I replaced them with led bulbs that are supposed to replace 1157 bulbs. Wow, that was a waste of money. The led replacement bulbs were not as bright as the standard 1157s were.

Then I did a lot of google research, and found some led replacement taillight assemblies here www.superbrightleds.com/cat/truck-trailer-led-lights/

I was lucky enough to find left and right assemblies that fit where my old assemblies did and could not be happier. Now people behind me KNOW when I am turning or stopping.

The tail/brake lights on my fiver are mounted inside the body cavity and are not separate fixtures that can simply be replaced. I went to SUPER BRIGHT LED's (superbrightleds.com)and purchased a square wafer LED which is attached to a wire with an 1157 plug that plugs into the trailer. Because of its size they have over twice the number of LED and are super bright. Be sure to purchase the red LED lights if you are using them with a red lens, white only if using with a clear lens. They are much brighter than the OEM bulbs and have the instant on feature.

I replaced the entire fixture on my previous coach, a 2001 Laredo. I did it for the increased daytime & nighttime visibility. Easy plug & play safety upgrade.

I changed to these Bargman LEDs because a socket was corroded when the trailer was new and the OEM lights seemed small. They get noticed.
