i know a few guys have done it on here, they had to take apart the circuit board, and i believe they needed a second set to circuit boards to take parts out off and such. and then they had to solder it all up..

Would not be hard to do on the Trailblazer truck.

Parallel the two filaments.

Connect the low wattage filaments (tail lights) together (these may be connected from the factory, check to see if they both light when tails are on),


Connect the high wattage filaments (one is brake, other is signal) together; by cutting the brake and signal wires a few inches from the light assembly. Splice them together.


Run a new wire to the trailer wiring and connect to the correct side (left side to left side, etc), feed the spliced brake and signal lights with the wire from the trailer wiring.


Note: we are using the trailering wire because we need to supply the brake and signal voltage on one wire.

Actual, it is, lol.


You check the tail lights (see if both light when the park lights are turned on), and I can walk you through the rest................ even if you have no electrical experience.

TXBlazer and Jetttstream have quad mods already for the back lights (signal & brake). :hail:

Saves you from screwing things up. Get their pre-fabbed, plug & play mods. :yes:



BTW, I'm running both their mods. :thumbsup:

I will have to add this to my list of how to's to produce. I did it for my Envoy, pretty much the same method for the Trailblazer.

The Envoy already has three lights:

Top = Turn signal
Middle = Running Light
Bottom = Running and Stoplight

IIRC, the bottom light on the TB is the back-up light.

What did you change on yours?

some one did send me a how to on trailvoy forums..but confusing as heck.. and then i just looked up jet as metioned above and not finding anything current and the website has nothing to do with any products listed by jet... and i did find a price of $164... but then still more parts were required?

Pretty sure the the Envoy has a different board style than the TB so it wouldnt be the same.

TB:

Top Light - Dual Function Socket - Stop and Running
Middle Light - Single Function Socket - Turn
Bottom Light - Single Function Socket - Reverse

I did a ton of searching on this at the OS and there's now way around having to modify the boards and make the center socket dual function.

I'm not sure about pricing - I've had these mods for a few years now. You'll have to get in touch with them to check on current pricing/availability.

BTW, Running both mods gives me:

Dual Brake lights (upper, middle),
Dual Signal lights(upper, middle),
Dual Park (upper, middle).

Just like the Chevy Silvy's of the time.

After the mod...

FYI - so far, the dual brake mod isn`t compatible with LED bulbs. That`s being worked on though.
