instrument panel turn signal bulbs

Took the dash out and repainted the needles. Also put new LED bulbs in. However, I cannot get the Turn signal bulbs to work. I turn on the turn signal or hazard flashers, and the light outside the car work as advertised, however, the indicators in the instrument panel do not. I've tried changing the LEDS around figuring I have the polarity backwards, but still no-go.

Any ideas?

Also, if I go back to the regular incandescent light, what bulb type do I need (the old bulbs broke coming out) I should be able to get them at the local auto parts store.....right?

Thanks,

GLenn

LEDs used as turn signals require a "Different" relay/actuator

Courtesy of SUPERBRIGHTLEDS.COM:

"Turn signal issues with LED bulbs

LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. Also, with stock flasher units, the turn signals may flash faster than normal (Hyper-Flash). These installations will require an electronic flasher unit, available in our car bulb shopping category (for some vehicles) or at your auto parts store. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often HEAVY DUTY flashers will also work with LED bulbs.

We offer some LED Flashers in our Tail/Brake Turn Signal Bulb category but we do not know which one (if any) will fit your vehicle. You will have to compare the pin-out of your flasher with the pin-outs of the flashers we offer, to see if we have a match, BEFORE you order one. Sorry but we do not have a flasher application list or the expertise to tell you which of our flashers will fit your vehicle.

Another fix is the installation of Load Resistors which are wired across (in parallel with) the turn signal bulbs to simulate the load of a standard filament bulb. We also have these available in our car bulb shopping category."

That sounds like it is geared toward LED bulbs in the external lights. I put LED's in the indicators in the instrument cluster and they do not work no matter which way I put them in. External lights flash fine.

I'd try removing them and applying a 12V source to the "wings" on the socket. If they light up I'd put them back in and rotate them in the socket (W/ signals on) until they light up. Sometimes the cluster is just finicky and the bulbs have to be in just the right position to work.

If the bulbs don't light when testing them in the sockets, check the bulbs directly. If the bulbs themselves aren't bad solder the leads to the socket.

Check this thread I had about LED's for the illumination bulbs in my cluster, maybe you're having the same problem I did.
