I keep having to replace headlight bulbs about every 2 to 3 months? I can't believe this is normal? I only use well known makes Osram, Phillips. Any suggestions please apart from not driving at night.

not touching the glass and what voltage does alt put out when engines revved

James - very careful not to touch the glass will check the Alt - what would cause concern? Last bulb actually blew apart with glass all inside headlight

Is it one particular headlight lamp that keeps blowing or any one of the four?
Do any of the parking, tail, brake, indicator or fog lights blow?

Any flickering before they blow? A poor connection leading to arcing could result in the lamp overheating and ultimately blowing, but unlikely to cause it to shatter. Check the multiway plug that goes into the headlight unit. Any evidence of arcing or overheating? The 'sockets' in the plug (the pins are in the headlight unit bit) can be pushed back into the body of the plug leading to a poor connection.
Any water getting onto a hot lamp could certainly cause it to explode. Are all the seals ok?

Nope. All looks normal. No sign of leaks or arcing.

Hi did you ever get to the bottom of this ? Mine had the exact same problem it not just blows the filament but either shatters them or melts a hole through the glass. I use Ring or Osram bulbs

Check the alternator output isn't too high. Sometimes an old and failing battery can cause the alternator to output too much voltage, on smart charge system cars.

I will have a look at that it did it for a while about 2 years ago and then went on a set of bulbs until yesterday so thought it was sorted. Really strange how it melts or shatters the bulbs never had that before its a 62 with the LED running lights. Never had an issue with my old 60 plate one which didnt.
