2002 BMW325i, on the dash, warning light indicating bad bulb

You need to change the bulb in the Left front lamp. I hope this helps. Take care.

Sounds like a possible bad ground connection.
Make sure the contacts for the bulb are clean.
Make sure the cround connection is not corroded.

The first thing to do for your dash lights is to verify the fuses, if ok check your lights dimmer next. Sometimes, dimmers fail to provide good contact due to wear or poor filament contact. Otherwise, there is a poor connection somewhere.
Usually, a rapidly blinking turn signal is due to a burnt bulb on the side in question or a bad ground connection either in the front or the back of the vehicle. Turn the left signal on and check if front and back turn lights are on and working if one doesn't work check the bulb. If it is poorly lit and not blinking check the socket and ground connection.
Hope this helps you!

Check the bulbs the dash lights will still come on even if the bulbs are blown. A good way to tell does the lights stay own are do they flash ?

ck fuse for rear taillights tis under the dash lower left of steering wheel. or if you still have the manual look in there under fuses.
also look for a bad ground but i doubt that.. if it's both rear out.
fast flashing well here's a chart with all sorts of info.
Problem What To Do Turn signals light, but do not flash Replace the flasher No turn signals light on either side Check the fuse. Replace if defective.
Check the flasher by substitution.
Check for open circuit, short circuit or poor ground. Both turn signals on one side don't work Check for bad bulbs.
Check for bad ground In both housings. One turn signal light on one side doesn't work Check and/or replace bulb.
Check for corrosion in socket. Clean contacts.
Check for poor ground at socket. Turn signal flashes too fast or too slow Check any bulb on the side flashing too fast. A heavy-duty bulb is probably installed In place of a regular bulb
Check the bulb flashing too slow. A standard bulb was probably installed in place of a heavy-duty bulb
Check for loose connections or corrosion at the bulb socket Indicator lights don't work in either direction Check If the turn signals are working
Check the dash indicator lights
Check the flasher by substitution One Indicator light doesn't light On systems with 1 dash indicator:
- See if the lights work on the same side. Often the filaments have been reversed In systems combining stoplights with taillights and turn signals
- Check the flasher by substitution On systems with 2 Indicators:
- Check the bulbs on the same side
- Check the indicator light bulb
- Check the flasher by substitution
hope this helps. may want to print for future reference. :)
hope this helps.

Yes - the fast flashing is a warning that a bulb is burned out. Change the bulb (be careful to put it in the same as the old one as it probably is 2 bulbs in one , parking and turn/stop) and you should be fine.

When signal lights stay on at indicators there's usually bad bulbs or the headlight switch is no good it's a self warning in the system check the bulbs for good elements if okay I'm pretty sure that the headlight switch is n / g

Bad earth maybe....have you tried a multimeter on the connectors with the ignition on and indicator switch on??

No there not connected, replace the brake light

As for the horn, inspect the fuse and relay and most common it would be a bad ground wire or worst a bad horn due to corrosion. Horn will be located in the drivers side fender.
Thank you for using fixya.

CHECK ALL BULBS, SOME HAVE A SLIGHT DARK SPOT ON THE BULB AND IS BAD AND FLASHER COULD ALSO BE BAD. CHECK THE FUSES TOO.
