LED oh LED, how I love thee....

Before my 11 Taco I leased an 05 off road one, didn't have led anything, never an issue tho, btw truck looks clean

 

Little update..... as I finished my lunch I grabbed a piece of pipe,towel and 10mm looking to burn rest of lunch time, im at work btw, using seat to apply pedal I walked back to verify what my wife told me and wham lights all lookin fine.

Maybe I'm dealing with gremlin, or wife getting back at me for wearing shoes thru house yesterday

 

Ha! My guess is the wire is loose where you tapped in for the camper shell. May be worth looking at if you're bored.

 

Punch her in the throat and tell her to get back in the kitchen

 

I removed scotchlocks, replaced with heat shrink butt connectors. Could be loose wire tho, dunno, I'll keep looking

 

Naa, I'll just have her hit brake pedal till her leg hurts

 

It's been awhile folks but I've finally got my answer!

I caused the whole problem,

After the cap was installed by a couple scotch lock lovers I that day cut out damaged wires and replaced with heat shrinking butt connectors. I've been a mechanic 18 yrs and am the first to admit I did not have more than a few strands in the connection before crimping down which prolly pushed them even further out, then shrank protective film and moved onto verify it worked which it did. Now many years later it's been intermittent in operation, so I bought an earlier model taillamp, and been rocking the two face approach awhile, I'm like a dog with a bone so I cracked open the led one to see inside
Toyed around with different paints to try and match the led output with an incandescent bulb only to realize it was a futile attempt . That's when I realized when I depress the brake pedal I lost the running lamp and the brake lamp did not even light up on that side so that sent me into looking why that's when I realized it was the old harness that's giving me the problems not the led assembly down inside

Needless to say I swapped harnesses with the incandescent harness and the led came on bright and happy as can be so I knew right then and there that I had made an error in my crimping .
