I had one on my last GN. It did brighten the lites enough to notice.
Do you really want bright? Holley Lite Bright LED stock appearing headlites are MUCH brighter, you don't need any extra wiring, and they have a much lower amperage draw than stock headlites.
No downside except the price, and LED lights last darn near forever!
These are the only stock appearing LEDs that I am aware of. No whiz-bang, Google eyed garbage that the LPBs love so much!
