I notice in your profile you have a diesel FR - be very careful - the diesels don't like LED rear lights - you'll get problems with the glow plug light flashing (a weird brake light warning that doesn't exist in the manual!). You can get around it if you et some resistors to bring up the resistance to that of a standard wattage lamp providing you're technically minded enough.
Do you think this will happen if you have swapped your side lights for LED? (and no, they are not neon blue!)
