I have 4 Octane Lighting headlights with relays which have Halogen bulbs. They have the outer LED rings that can be used as a running light or for extra brightness. You can put in LED bulbs if you prefer. I have one switch and you will need to get another switch if you want all 4 LED rings to come one. I had them for about two years, they maybe have 50 hours on them. I went to Holleys new LED lights. 100 bucks, you pay for shipping.
