One brake light quit working

Recommended Posts

1992 Loyale

Drivers side brake light just stopped working. New 1157 bulb; no change. Drivers side tail light and passengers side tail and brake lights work fine. Any ideas?

wiggle the pigtail connector where the lamp assembly plugs into the body harness. Is it only the brake lamp not working? Is there a trailer hitch wiring setup?

I would suspect if the pigtail is not loose or corroded, one of the pins in the socket has either corroded, or came disconnected from behind. Bulb sockets can and do wear out.

 

My eperience working at u-haul, most of the time qa bulb was unresponsive, a wiggle of it in the socket would get it to come back. Sometimes the sockets had to be replaced from wear

 

I would suggest wiggling the bulb or pushing down and turning a little while someone stands on the brake to determine if it is the socket or something else.

Ground wire stuffs into the socket and is pinned agianst the outside of the metal "barrel" that the bulb fits into.  Sometimes they ground wire needs pulled out, cleaned, adn stuffed back in against that barrel.

 

Although....since your tailight works on that side, it's gotta be on the + wire to the brake light.
