Had an intermittent fault on my rear reverse/fog lights (I have LED combined red/white bulbs in a stop/tail light fitting). Stripped down the light and a combination of poor manufacturing tolerances on the new light fitting and softer aluminium body on the bulb means that it keeps wagglng loose.

Am going to solder leads to the bottom of the bulbs and then wedge them in the fittings.....
