I'm away with work at the mo but when i get back I Was thinking about replacing the interior bulbs with LED items as my colleauge has them in his S-Class and they look excellent! I already have LED sidelights and number plate lights which work fine. However I have heard that due to the low impedance of LED bulbs theres a chance they wont work/will flag up the faulty bulb warning? Is this true? Has anyone put LED's in there interior? Do I have to use a resistor to make them work to increase the impedance? They work fine on the sidelights/plate lights with no issues....And has anyone got any links/reccomendations on where to get them from as I dont fancy paying a tenner for 2 like I did for the plate lights (halfrauds!)....My car is a 1998 B5 Avant.
