Change them out to LEDs, too

 

Watch on the signal bulbs though, you may need resistors wired in if you use LEDs, otherwise the computer will think them burned out and they'll "hyperflash", flash really fast.

 

ftmfw.

 

led bulbs didnt hyper flash in my 97...just for thought, leds work just fine, no shorts, no thrown codes, plug and play works just fine

 

Sorry Viper, you're right, the relay, not the computer. Thanks for the correction.

They didn't work in my 2001. Hyperflash.

 

tried them in my 99 hyperflash, i have resistors just didnt feel like wiring them up
