Guy,
You might also avoid touching the H4 bulb with your bare skin...something about the oil in your skin that it doesn't like. A little swab of alcohol will take care of that.

Thanks for the tip !!
I did try to be careful,but my arm might have touched the bulb.
I'll try the alcohol swab.

The wife works at the local hospital.
She brought me some alcohol swabs home today,so I wiped the bulb off real good.

you're correct, if oil gets on the bulb glass the bulbs get super hot and blows them

another tip if the lens gets a little foggy from moisture use a hair dryer or heat gun but careful with the heat gun to dry up the moisture good luck and have a good day Jeff from Winnipeg

I make sure I do not touch the bulb but I wipe them with alcohol just the same....I also use dielectric grease on all the connections to keep moisture out of them.... :popcorn:
