Under hood lamp

[Chevytruck98]

So ive got an issue here, my underhood lamp doesnt turn off when i shut my hood. It stays on. Im just curious could the switch be bad that is supposed to turn this off. I was just going to replace the hole lamp. I called gm and they said it is no longer sold. Any one have any idea's on what could be wrong.. or where i could find another one?

Those lights work with a mercury switch. When you open the hood, the mercury rolls back to the contacts to complete the circuit. May need a bit of adjustment. Try bending it down, with the hood open, till it shuts off, then bend it back up a bit till it comes back on. Check to see if it goes off when you close the hood.

my lamp turns off but when im going down a bumpy road i can see it trun on and off every time i hit the bumps in the road. could this be the same probablem with the switch?

Could be. With a 4by, & a bumpy road, it could be throwing the mercury around so that it's making contact just long enough to make the light turn on. Probably have to bend it down a little more. You can adjust it so that the light just comes on just at the last couple of inches of the hood's opening travel.

If im right, all you have to do is bend the light it self down untill it turns off?
