what indicator my right one
Check the bulbs one of the 2 filaments may be burned out
if they are daytime running lights you can not shut them off without pulling the fuse. but if you are parked and want them to go off you can apply the emergency brake and they will go off til you let off the emergency brake.
i found it to be the tail light harnesses go bad . a common problem with them because the bulb sockets short out.
Often this type of behavior is caused by a bad ground for the lighting circuit. Check the ground circuit for the brake lights.
Is it the taillights or the brake lights? If taillights it may be a wiring problem, If brake lights check the switch on the brake pedal
Make sure the parking brake is completely released. If the parking brake is on the Highlights go off.
Make sure the emergency brake pedal is retracted all the way up. Or check the switch at the E brake pedal. The headlights go off on all 1999 tahoes when the emergency brake is on.
use your parking brake this answer is in the owners manual
slightly press your E brake on just enough to make the lights go off but not enogh to wear on the brake. this worked on my 97
Press the emergency brake in very slowly. And watch when they go off. Have somebody watch when they go off.
Brake lights should NOT be effected by the headlights. Brake light function is completely independent of the headlights. Assuming you are not refering to the tail lights, or marker lights, which are supposed to come when the head lights are turned on. Not having brake lights when the head lights are on is a big safety problem and should be corrected.
The Kia Sorrento instrument panel lights go on and off with the headlights. The headlights go on with an automatic daylight sensor.
