running lights contact or lack of?

[Newkie]

Just wondering if there is a trick to creating a good contact from the bulbs to the socket for both front and rear running lights. They are very sensitive to movement because of how loose the bulbs sit in the sockets.

Thanks

Hopefully with this difficult description I was trying to explain, you understood what I was asking?

Shim the socket spring to put more pressure on the contact area.
Polish the contacts on both the socket and the bulb.

If that is a roblem, I use my soldering iron and put a bigger glob of solder on the back contact(s), file round, cleand everyting, and it generally works.

On older cars, I often find that to fix even an older bulb, but it seems the vibrations and road "bumps" often wiggle the bulbs around and wear down those contacts.

I have one Lucas socket that the long, skinny contact area in the socket has shrunk a bit into the phenolic.
The solder blob fixed that, too.
