S13GE, thanks for the listing of all standard fit lamps for the 500; I will look into the option of the 8w DRL 'upgrade' as that seems to produce a brighter, clean, white light in daytime use. Interested to know if anyone has upgraded the interior and boot lamps from standard 5w to something brighter, without melting the fittings, or whether there is an aftermarket exchange unit (e.g.LED) that anyone has found?
