Underhoodlight

Over the years on my visits to the salvage yards, I almost always get the underhood lights when I can. Out of the (12) I had, only (2) worked as they should when properly connected.

What I found out is (when I take them apart) is that little bullet shaped mercury switch seems to go bad. If I short it out, the light works fine.

Question: Is there any where you can still get these little insertable mercury switches? They kinda remind me of small bullet.

Otherwise I will have to end up jumping the switch and sticking a mercury switch from a 87-92 inline w/ the light harness somehow. I did a search on underhood light, but really did not find anything.

Thanks

At the parts stores they have these little auto trunk lights you can buy to add to your car. I had one of these, and it had the little mercury switch inside it. I don't know how much they cost, but it might be worth just buying the light and taking it apart for the little switch.

I just called the tele# listed. Left a message on the contact's voice mail. Apparently, this FREE replacement of the mercury switch is a Grant from the US EPA. sounds like a win-win. If I found out more, I'll post the info. Maybe for NY though.

Interesting. So do we have to send in our mercury switches to them to get a ball bearing switch? I was gonna remove the light from the hood(replacements=$$$$), but if this works I will keep it.

This is more silly stuff from our great government and the tree huggers. Mercury is a bad thing for the environment, and they are trying to get rid of it. On the other hand, they are wanting to force you buy those little curly fluorescent bulbs to replace your regular incandescent bulbs. Guess what all fluorescent bulbs have in them? A little blob of mercury.
