pingpongpo Posted February 21, 2007 Report Share Posted February 21, 2007 Hello everyone, Does anyone know if there is an issue with rear lights on Mk4 Golfs blowing regularly? I keep having to replace the nearside lamp every 6 months which is far too often for my liking. As a footnote, I drove from my work to the garage last night to get some diesel, probably about 2 miles with my lights on (remember that the light has already blown) and removed the bulb to check what type it was and it was hot to touch!! even though it wasn't on!! I assume this means that there is some sort of faulty electrical connection going on here or could it be something else? Any help would be greatly received, sorry about the rambling......its just a pain in the arse to have to keep replacing it and I also got pulled last night by mr plod because of it.....rambling again......

sotty Posted February 22, 2007 Report Share Posted February 22, 2007 I have the same problem with my 2001 Golf MkIV GTTDI. It seems like Im always changing them. However, it may be down to the quality of the bulb. I usually dash into the local petrol station and buy cheapy "Ring" type. I'm going to try a better type in future and see if they last longer.

pingpongpo Posted February 22, 2007 Author Report Share Posted February 22, 2007 I can't remember the brand I normally buy but I've bought some different ones this time. I normally replace both sides at the same time incase they are slightly different brightness. Link to comment Share on other sites More sharing options...
teash Posted February 22, 2007 Report Share Posted February 22, 2007 Your not alone on this one my friend because I have the same problem and use a decent brand of bulb, infact next time you spot any Mk4`s out there i`ll guarantee have of em either have a stop or tail light out Link to comment Share on other sites More sharing options...
pingpongpo Posted February 23, 2007 Author Report Share Posted February 23, 2007 I looked into this a bit further and it seems to some of the technical bods where I work that the bulb is 'over voltage' because instead of the filment just burning out, the inside of the glass has gone completely silver and if you look carefully is actually glowing a tiny bit when illuminated. This is a symptom of over voltage apparently but I haven't had the chance to get my multimeter out yet. Link to comment Share on other sites More sharing options...
sotty Posted February 23, 2007 Report Share Posted February 23, 2007 Come to think of it , mine have had a slivery coating on the inside when Ive changed them. It also happened with the front side light bulbs too. If it is over voltage, what would be the likely cause? Link to comment Share on other sites More sharing options...
pingpongpo Posted February 24, 2007 Author Report Share Posted February 24, 2007 I would assume the alternator is pumping out too many volts as the battery will obviously only give out ~12V. If this was the case though I would expect every single bulb in the car to be the same though. Link to comment Share on other sites More sharing options...
mb Posted March 19, 2007 Report Share Posted March 19, 2007 Although not an answer have you considered LED bulbs - I have run these in mine for a few years now without any issues (had to enlarge the fitting slightly to make them fit) I got mine from ultra leds ?
