They are run on the vehicles 12 volt dc electrical system.
There are a number of things that would make a volt indicator light to come on in a 1998 Buick la Sabre. The main reason is voltage feedback or a problem with the alternator.?æ
Buy Sylvania Bulbs, 7443 type 12 volt
I would check the brake light switch first. It's a common problem. The switch is located down on the brake pedal and is easy to change. Use a 12 volt test light to check for power at the switch. You've changed the bulbs or checked for voltage at the brake light sockets first?
Check your alternator, Mine did the exact thing. The Battery light and the !!BRAKE!! Light came on and couldn'y figure it out for the hell of me, did volt tests while running and only had 12.5 volts on the battery. I changed the alternator ($179.99) and got back to the normal 14 or so volts while running and lights shut off. no idea why the brake light was on at all.

Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.
Brake Light Switch (Found Mounted Underneath Dash By Brake Pedal) Bulbs Or Sockets Are Bad (Use Test Light To Determine) Wiring Is Bad Connecting To Sockets. Check Fuses With A 12 Volt Test Light To See If It's Just A Bad Fuse. Buy A Chiltons Book For Your Car, You Can Repair A Lot Of Your Minor Problems With This Book.
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
Right turn/brake - green. Left turn/brake - yellow. Running lights - brown. Chassis ground - white. Reverse light - purple. 12 volt hot lead - black. Electric brake output - blue.
Yes, a 12 volt auto light bulb can work on 12 volt AC, but the light output might be slightly lower compared to when using DC. The bulb will still produce light, but it may flicker due to the alternating current.
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
Yes, a 120 volt light can work on a 110 volt power supply without any issues. The difference of 10 volts will not significantly impact the function or performance of the light.
