Default LED bulbs in rear.

So I replaced my rear turn signal and brake bulbs with Leds. Got the rapid flash and installed resistors to fix the problem witch it did. But still when lights are off and you depress the brake pedal the interior lights dim and the parking lights come on... does anyone think I have to install resistors on the brake bulbs as well?

Default Re: LED bulbs in rear.

I did not use resistors. I did the flasher relay mod posted on the SRT forums.
I check the pictures are gone.
But maybe you can fiqure it out with out the pics.

Quote:
First, remove the flasher relay from the multi-function switch by removing the 2 screws from the bottom of the cover under the steering wheel.
Next, You will see two tabs on 1 side and 1 tab on the other side holding the cover of the flasher in place. carefully pry this open so that the circuit board is exposed. (i wasnt so careful)
On the back of the circuit board, you will notice a small IC Chip with 8 pins coming off of it. There's is a referance notch in the white line going around it to mark the "top" of the chip.

Pin layout in the picture is as follows

5 4
6 3
7 2
8 1 (note pin 7 trace and pin in red)

Pin 7 is the Lamp Failure circuit, which is what causes the ricer flash when replacing bulbs with LED's. This is the circuit we are going to disable. To do so, take an X-Acto knife and either break the pin where it meets the circuit board, or cut through the copper wire on the circuit board itself to make sure that it is completely disconnected.

Once you've done this, put the cover back on, reinstall into the multi-function switch, and you're DONE! NO MORE FAST FLASH!

I realise this will defiantly upset some vendors now that they dont get to sell their resistors anymore, but in all honesty, this is the SAFEST solution to fast flash...

That's peculiar. Is your PT an '06 or later? I'm thinking CanBus is confused about your LEDs.
I changed my running/brake bulbs to LED and zero issues, bt I have an '05.

Changed mine to LEDs in the 2006 GT vert and the 2010 Couture with NO ISSUES! IPCWs from Maggie, at Race&Street.

Problem may be that you just replaced the individual bulbs, rather than getting the whole aftermarket tail light assembly.
Odds are that the companies like IPCW that sell the LED tails have included resistors, etc, in the wiring consider the problem reported early on with LED compatibility in early PTs.

As in....
Race and Street: Chrysler PT Cruiser mirror covers 2001-2002 (with folding mirrors) - Autotecnica

Of course, I got mine back when they were around $160!
You might want to keep an eye out for someone who is parting out a PT with them; or used LEDs "for sale" posts.

Could you have disturbed the wiring when you took the tail lights out???
