led conversions problems

[cplanubis]

I'm new here and have been looking for threads on led conversions on the rear lights but cant find any that apply to my problems

i did the conversion and the driver side brake/tail/turn (the middle bulb) does not work. I did some research and the socket plug is a non-typical 3057 socket. Both power leads are on the same side. With the typical, the power leads are on the same end. Everything on the passenger side works fine.

Anybody have suggestions?

OK did some testing on my truck the pass side is a standard socket and the driver side is a ck socket
i ordered the socket boards from LCM a few months after i bought the truck

 

[cplanubis]

well there are 3 choices for the conversion
1 put in non polarity leds

this is the one i chose

2 after market tail light housings that don't have the boards so you can rewire them if need be

3 after market led tail lights

if you know of any other wasy please let us know

I think you're misunderstanding the problem a little bit. Yes, the middle socket on the circuit board is wired differently. The direct solution is to use an SRCK-type LED in that socket. Most of the auto-LED vendors offer them. A non-polar LED is not the same thing. Go to whatever vendor you please and search them for SRCK.

let me know where you get the srck led and if they work please

i went with the non polarity leds
but if i do decide to switch over to the srck leds ill let you know how they work out

what do you mean, non polarity? from what ive seen the only ones that will work are the ck's in the turns

Amazing how what to buy is well-documented and people gamble with other stuff anyway.

SRCK LED's have been around for 15 years now, developed specifically because of GMT400 trucks. Not trying to pat myself on the back here but a story I have told here before, I bought a set of some of the very first 3157-type LED replacements, from a company called Hz. Engineering. They almost literally went up in flames when I installed them in my old white '92. Sent pics of them and the taillight circuit board, with notes on the circuit diagram, to the guy and he came up with a new version of the bulb specifically for that location on the truck. Since then, this style of LED has been available to us, offered by just about every company that sells automotive LED's (V-LED's, Superbright, Autolumination, DDM, etc.) since not just GMT400's use this stlye - a few other models made after that are wired this way, too.

But, do what ya like.

Basically they are dumby proof they can be installed any way
