You fit new pads and the light will go out after 2-3 starts.
there is an adjustable brake light switch under the pedal.
I would suspect that the brake pad warning light wire has lost part of it's outer insulation, When you turn the steering, the wire is most likely shorting to earth which will cause the W/L to illuminate on the dash.
Normally this is caused by a defective brake light switch or one that is out of adjustment.
Open tailgate and you will find two bolts that hold brake/tail light assembly in place. Remove the two bolts and the assembly can be pulled out. Turn the brake light base counterclockwise a quarter turn, pull the bulb out directly, snap the new one in and then re-install the light assembly unit.
In general, you can't.
the light can come on when the gas cap it not fully tightened to at least 3 clicks
No , the rear brake lights do not turn on when you use your parking brake , just the brake light on your dash is supposed to come on
I open the brake fluid reservoir lid off, check brake fluid level, and put back the lid. Brake light goes away. Seems the plastic float on the lid is not operating correctly in cold temperature.
In many cases, the brake light and the turn signal use the same bulb.
Behind steering wheel is a set of contacts that disable the brake lights when a turn signal is on, they may be stuck in the off brake light position. Try pushing the turnsignal arm to its limit and then wiggle it....careful you do not brake it off. Also check for brake light switch adjustment.
If it is a single bulb, it is probably the bulb. Many tail light bulbs have two separate filaments, with the turn/brake being much brighter than the marker light. The tail light and turn/brake circuits are completely separate.
Open the turn there is a little hatch take it off twist the light out and pull the bulb put the new one in simple.
