Weird issue after installing led bulbs in tail lights.

Weird issue after installing led bulbs in tail lights.
I swapped out my rear bulbs for LED bulbs, and now when I step on the brakes, my gauge cluster lights come on, and when I put on my right turn signal, both rear lights will blink, but left turns are fine.
I like the brighter tail lights, but it's not safe not being able to use a right turn signal, and I don't need to be pulled over because of it.
Any idea? Do I need to add an electronic flasher maybe?

since its all about the circuit resistance, if I remember correctly all the wiring rungs down the passenger side then over to the driver once it gets into the trunk. More wire equals more resistance (or in this case just enough to make it function as normal) as opposed to the shorter wires for the passenger side. Just a theory but one thats possible. you would likely see a difference if you ohm'ed them at the socket if this were true. But just mimicking the resistance of a the old filament bulbs with a line load should fix you right up.

its fine to put the resistor next to the socket you are putting led in. cant remember if you need one for each socket or just one on the circuit for the lights. though may want to pm whitebird00 he is the electrical guru with these cars, and has helped me out on a few occasions as well..
yeah not getting the correct resistance on a system that monitors resistance as a check makes for some funky stuff.

You have to add a load resistor in parallel to each LED bulb you add to the system. For turn signals, make sure you have one per side (doesn't matter if it's upfront or in the back). With stop lights, one on the left or the right should be enough, since it's all one circuit. The resistor is needed for the old school flasher to work. Otherwise it will not see enough load on the circuit for it to start flashing. The brake lights need a load as well, for the cruise control system to work properly.
If you look at amazon, you can find prewired harnesses that you could just add in series to your tailight sockets. For example:
Make sure you get the right socket though. 74440 might not be it for Trans AM's. Not sure
Get one of these for the rear tailights for the turn signals.. one on each side. Then get another for the brake light system. One should suffice.

So the bulbs that I removed, the original factory ones... believe or not, were 3057. That link only had 3157 adapters, and they won't fit into the housings. So back to square one. I really like the brighter look of the led bulbs, but I'm not sure they are worth the hassle at this point.

All you have to do is search some more... it's really not that hard
