what is the light on 1987 420sel dash that is yellow...circle...with 3 dashes on each side of the circle???

is it brakes or alternator/charging system??

lyle

Front brake pads warning. Means you've not got a whole lot of time before they are worn all the way down. I'd check them/change them...and the rotors too if those are worn out as well.

I think that is the light that tells you that a marker light is out. depends on what side it is on


I have said light on since one of the lights for the tail lamp is not seating properly due to the plastic lens being cracked and not holding in place

Brake pad wear indicator.

Lyle, as mentioned it is the brake pad wear indicator. As far as the urgency to replace the worn brake pads, it depends on what type and how many miles you drive in a week/month. I typically try to replace worn pads within a month after the indicator illuminates, and there is still plenty of pad thickness remaining. Pull the wheels and check the pad thickness. Obviously you want to avoid wearing through the brake pads and have the backing plates score the rotors. Remember to buy/install new wear indicators with the new brake pads.
