Well, after nearly 2 weeks of having the LED's in the clocks I was a bit disappointed. Initially they were great but the first bulb went after 4 days, I replaced it (I got 10 bulbs in my pack), the same one went again a few days later and on Friday night one started to blink on/off while stuck in the traffic during the M6 closure - eventually giving up the ghost a few miles from home, leaving me with a single clock light. I replaced those but one of them wasn't working last night so this morning I put another in.
It wouldn't work, so tried another and that worked. I then realised that the one that was now working was one of the original "blown" bulbs I had replaced earlier in the week. I took a closer look and found that the T5 LED bulbs cause the plastic bulb holders to flex when they are inserted (well the ones I have do) because the plastic chassis is thicker than the std glass bulbs. It's not much but you can see it, when it flexes it makes the little copper contacts lower than with normal bulbs so the contact on the PCB is less. I bent them up slightly with a razor blade and now they all work, even the ones I thought had blown.
Will see how they last.
