I installed a couple Jon Hass LED lights and highly recommend them. WOW! what a difference. The headlight high/low indicator was very difficult to see before, great now. And the tachometer face light was poor, I would strain my eyes to read numbers, again not know the LED lights it up great. I am very happy with my purchase. Note: The difference in thickness of lamp to LED circuit board requires tweaking the socket contacts to obtain snug fit to board.
