sounds like you've got either a bad ground, a grounded hot wire or maybe just a bad bulb. Try another, then if that blows, check the voltage going to the bulb. Also, check for frayed or damaged wires.
A signal that is blinking fast usually indicates a bad bulb or bad flasher. Check to insure all of the bulbs burn, then check the flasher.
If you added more batteries in parallel, then the bulb would shine for a long time. If you added more batteries in series, then the bulb would burn very brightly for a short time and then 'burn out'.
It means that it is getting ready to burn out...just replace the bulb and it should stop. Either the front or rear turn light is no longer working. Change it out with a new one
If a light bulb is handled roughly before it was installed, the filament holder could have been weakened. Another reason that bulbs burn out before their time is that they are being submitted to a higher voltage than the bulb rated for.
Be careful not to handle the bulb with your bare hands. The grease from your fingers will effect the life span of the bulb.
Sounds like you need a new flasher.
If you added the batteries in parallel, then the bulb would stay on for a long time and nobody would get any sleep. If you added the batteries in series, then the voltage across the bulb would eventually become excessive and the bulb would burn out.
simple, there is an access panel in the front wheel wells of the BMW 328i.just take the access panel off. there's a tab that you have to twist to get the bulb off. there are no wires coming from the bulb, just the tab that needs to be turned. avoid touching the new bulb with your fingers as they contain oil, which will cause the bulb to burn out prematurely.:-)
By bulb, it is assumed a light bulb is intended rather than a flower bulb or any other kind of bulb. Light bulbs burn out because they are engineered to do so. There would be less profit to the bulb manufacturer if he made bulbs to last longer, which he could if he wanted to. In the early days of bulb manufacture, a bulb was made which still continues to burn over 110 years later. See the link below for more information on the 110 year bulb.
The bulb will burn for 15 minutes.
A fast flashing turn signal, on most any vehicle, is an indicator that a turn signal bulb is going out or has gone out on that side(i.e. front turn signal on passenger side flashing fast, check the rear turn signal bulb on passenger side.) This will cause the light on your dash board to flash fast as well. This is generaly a good time to replace all of the bulbs, turn signal, running lights, and break lights, as they are so cheap. Also check deck light or top break light if applicable for burn outs.
The filament (assuming an incandescent bulb) would burn up very quickly.
