[QUOTE="Revved Up Sparky, post: 292162, member: 5050"] In my humble opinion and experience the problem of light bulbs having a short life is often down to two main causes :- i) Inferior quality light bulbs. ii) Excessive wear on lampholder contacts. Deterioration of spring tension will cause a poor connection between lampholder and bulb, a higher electrical resistance and thus a build up of excess heat. I would start by trying high quality light bulbs, then perhaps inspect (with power safely isolated of course !) the lampholders for signs of wear and replace any lampholders/ light fittings that appear to be in poor condition. There may be a less common cause but I personally would try those two first. [/QUOTE]
