LED Tail lights

No photos here:

I wanted brighter tail lights, the OEM incandescents seemed not very bright.

The culprit turns out to be the 80 feet of wire in the loop.

the batteries are at the back of the coach, power needs to feed forwards to the switchgear, and then thin wires come back to the tail lights.

we were seeing around 9v across the bulbs..

So I thought.. lets get soem LED bulbs.. that would require fewer amps less Vdrop in the wires... win win..

not so fast...
It seems that the LED bulbs didnt like the long runs either.

some lesser brightness ones would possibly work.. but the absurdly bright ones I found on amazon failed.. flicker/flashing or just not turning on.

with a solid 12v they were great...

Solution was to run a direct 12v feed to each tailpack and have 5 relays in each corner that are switched by the signals and that select the direct 12v feeds into each bulb as needed.

Results:

Super bright leds...

and I can hang more lights on here with no worries about overloaded switch gear.

lots of side markers, huge reverse pods...
