Default Under hood LED loose connection

I’m in the process of switching all of the bulbs on my C5 over to LED’s. It’s all LED now, except the tail lights, which will be soon.
I’m having a slight problem with the under hood light. It seems when I open the hood it burns very dim. But when I start the car, it’s very bright as it should be.
The bulb doesn’t have a good tight fit like the stock bulb did. I’ve seen posts where this is a common problem with these LED’s. I can tap the lens and it’ll flicker a little. What can I do to make it a little tighter connection? Any other LED’s for the hood light you guys recommend??

Question, does the light stay on as long as the hood is open? Reason I ask is the light never worked since I bought the car and kinda good thing because I leave my hood open for days at a time.

Yes, my light stats on for a little while, then it times out. It’s always worked perfectly before I put these LED’s in

With a functioning bulb, the light goes off on a timer if the hood is left up.

You need to install a resistor to adjust the voltage. I had the same problem: open the hood and the light would be dim. Someone suggested that if I opened a door or flipped open the visor mirror lights, that it would brighten up (they're on the same fuse). Sure enough, the light immediately became bright.

Before I would mess with a resistor for an under hood light, I would just buy a bulb that functions properly.

Would you happen to know which bulb will eliminate the problem? I bought what I thought was the right one. Thanks.

Have you looked at Vette Lights and Sharplight - both forum vendors?

I actually don't remember from where I ordered the bulbs. I replaced all the interior lights and the hood light. All were nice and bright until I got to the hood. It was bright at first and then was dim when I checked it later. Thanks for the recommendation.

They're available at auto supply store, but you might want to take Ed Ramberger's advice and look for a different bulb.
