I can't remember what number bulb I am using at the moment but it is used for a low beam headlight in some of the trucks we work on at work. Maybe I can look and post the number. The plug is the exact same plug. It won't lock in the housing so I sealed the light to the housing. It makes changing them a little tougher but I have only had to change one of them since I did this about a year and a half ago.

 

I found a 27w replacement. Is something like this good?

It says these are Super Bright Xenon gas filled halogen bulbs. I don't want it to be an annoying white/blue. I like the incandescent look to match the stock headlights. I'm having a hard time finding 27w ones from Napa/Advanced Auto
