To replace P13w bulbs without drilling or reaming. Remove outer cover by inserting a screwdriver against a cloth, between the foglamp glass and plastic cover. Gently prise the cover away.
Remove three screws and unclip the two connections.
Remove the standard bulb and replace with the LED, this will not push into the hole completely.
UseGlasticon putty (Dum Dum) - not you the putty, and seal the bulb into the housing.
You can replace the standard grey (why) covers with chrome ones.
These fit on top of the originals and are held in place by one chance only 3m tape.

End result looks great and costs pennies.
