HID and Ballast help

HID low beam and fog bulbs burned out at different times, replacement bulbs did not work. Fuse looks good. Curious about ballast, I am not the original owner and the 2010 truck had previously been wired for HID.

My question is some ballast are 35 watt others 55 I believe, not knowing the wattage of the existing ballast does it matter what wattage ballast I purchase to re-install ?

 

I have HIDs on my scooter. They are digital ballasts and you do have to match wattage, bulb to ballast.

 

Awesome, thanks. Just placed my Amazon order.

 

Not true. You can drive a 35w watt bulb with a 55w ballast. It will simply over drive the 35w bulb, making it brighter and shorten it’s life by 20-25%. 35w ballast are the norm though. Just don’t buy junky Chinese ballast and you’ll be fine.
