Thread: Pontiac Grand Prix LED Turn Signal Bulbs! Plug & Play Install!

Pontiac Grand Prix Front Turn Signal LEDs

From the factory, turn signal bulbs are powered by standard incandescent lights that light up amber in color.

Newer luxury vehicles are using LEDs for turn signals, because LEDs offer a crisp, instant on/off, increased brightness, and true, vibrant color. By replacing the bulbs in your vehicle, you can achieve this modern look!

You can even add functionality to your vehicle with switchback bulbs! These light up bright white for running lights instead of dim amber, but still blink amber when you activate the turn signals, for a unique dual-color effect!

Resistor Option: Some vehicles may have fast-blinking issues when LED bulbs are installed as turn signal replacements. We offer resistors to remedy this issue for a nominal charge. Alternatively, we offer plug-and-play flasher modules to regulate the flashing speed.

Free bump. looks awsome paul will be sending you an order when i save up enough to get a bunch of bulbs from ya.

Paul are these the correct bulbs for say a Regal? I see them listed as fitting any, the Regal has an oddball wiring of the socket that requires a special bulb type. While regular bulbs all fit, this is key with LED's.

Yes, I found out the hard way.

Anyone know which flashed we need?

Found it, ep28..do you guys have it too? It wasn't on the list of resistors

They r nice! I like these better than the other brands out there, in the vid. they switch from white to "amber flash" then back to white!! A+

Thanks! Available for sale now.

I am not 100% sure- to check, just remove one of the turn signal bulb, and see what the vehicle does. If it's fast, it'll be fast with the LEDs installed.

got mine ordered...well once the money makes it from my bank acct to paypal.

Not sure if there's enough interest, but I'd need 10 for a GB.
