both my low beam headlights are not working, but I checked the two fuses for the RH and LH low beam and they are OK. Suggestions?

It sounds like you have a switch that is not working here is a guide to help you see where you lose power and the headlight wiring diagrams so you can see how the system works.

First, what are the stock headlights for this vehicle? Can the promax ballasts be replaced with another brand ballasts without replacing the whole head light system?

Hi FELICIA,

Its best to replace the ballast with the original replacement for the manufacturer. If there are better performance ballasts we have no information on that. Please let us know what you find out so it may help out others.

Best, Ken
