Light does not go on

Repacing the bulb does not solve the problem. I suspect the part the bulb mounts onto makes poor contact - how can Ibe sure

Yes, very often it is the lamp socket that has failed. Contact: Delta Optical Instruments, Inc. Email: robin@deltaoi.com

    You can test the voltage before it enters the lamp socket with a voltage tester.

    It needs to be set on DC at something more than 6 volts.

Brake lights go on but when headlights are on and i press the brake they go off the brake lights go offf


Brad V's "bad ground" is most likely cause. I'd start investigating with the tail lights. (Not the headlights, but they may also be an issue.) Confirm all bulbs on both sides are good. That includes running lights, brake lights, turn signals and reverse. Some bulbs may have dual-function, the 3157 bulb in the J2K is one that serves stop-light (brake) and tail/running lights. Replace if suspect. Make sure the bulbs are mounted correctly. Rust can cause a poor ground so you might have to replace the socket or fixture if it is grounded to the fixture. By any chance do the turn signals also have issues? Or the emergency flash switch bulbs?

Left rear turn signal light will work and then stop I have to take the bulb out and put it back in tried swapping bulbs now the turn signal and brake light are not working


There could be a few different solutions;
1. the socket wires could be bent. Remove bulb and check for socket wires pushed into the socket housing. Use a small fine point pick to bend wires until they stick out into the bulb cavity.
2. The bulb wires could be out of alignment. Bend wires until they stick out from the bulb base.
Those 2 possibilities apply to the glass tang base bulb. If you have a metal base bulb ( it has the contacts on the bottom, with a metal base and pegs sticking out the side ). If this is your bulb style, you'll need to look at the contact points in the bottom of the bulb socket. If the contact point tops are flat or curved in, or if they are not clean ( green or brown corrosion on them ) you'll need to clean and re-grease the contact points before considering replacement. You can use either electrical parts spray ( recommended ) or a warm water and baking soda mix ( a coffee cup filled 3/4 up with warm water to a tablespoon of baking soda. Dissolve baking soda in water, make sure key is OFF and socket is away from other wiring. Pour a small amount into the socket and scrape contact points and side wall with a fine point pick or mini flat bladed screwdriver until contact points are clean ).
Dab a small amount of Dielectric grease onto the bulb base, covering the contact points and tags sticking out of the side, and re-install bulb, then test, If it still doesn't work, you'll need to replace the socket assembly - available from your local auto parts store.. Make sure you get a socket with the same number of wires and mount configuration.
Hope this helps!!

The problem is suspected to be the 'contacts' at the base of the bulb socket/holder/fixture - poor contact. If the contact point overheated and it melted (then 'sank' into its holder/fixture, then replace the bulb socket.

The high mount brake light has its own fuse, so check that first. The high mount bulb is generally a stabdard type (there may be more than one bulb) or you can replace with an LED. As for the left rear bulbs not working when depressing brake pedal, check the bulbs again for any spring that may be broken. If the bulbs are still good, make sure there is sufficient contact with the socket. If still not working, have someone check it out further.
