Hi there, One of my number plate lamps went out. On inspection, the buld falls out into the boot along with wiring and some plastic. Looks like the bulb holder has disintegrated. See they are still available, which is good. Surprise that these fail though, pretty well protected.
Funny that , I've just ordered 2 of Ebay today for just over £5 each. The only thing is I didn't have any there, it was only when it failed the M.O.T I realised. Just type TVR Chimaera number plate and you will find them straight away
