So I've gone and put LED replacement bulbs in my tailights/brake/rear turn signals. Everything works fine, with the exception that when push the turn signal stalk left or right, the indicator light on the tach blinks once and then goes out. The lights still blink, but it's not indicated by the green light at the dash. I'm assuming it has something to do with lower resistance? Is there an easy fix other than going back to the stock bulbs?

Did you replace your turn signal flasher when you did the LED update? Old flashers are NOT equipped to handle the low voltage of the LED bulbs. Go to Spokeworksled.com and get you a new flasher.

Toward the bottom left. Ensure you order the right one for your year.
