Finally I'm done with LED bulb replacements having just replaced the DRLs and Fogs with some I sourced direct from China - they needed to be slimmer and shorter than all the others I have seen/tried and I wasn't prepared to get the ones which don't come covered and are basically a bare circuit board stuck on the end of the base. The new fogs were perfect and went in without a hitch, the DRLs were slightly more of a pain as the small rubber seal around the base was too large and prevented the bulb going in far enough. I tried the seals off the original bulbs but were worse, so in the end I cut a thin strip of duct tape and stuck that around the base which made it a snug fit compared to no seal at all. When the wetter weather is upon us I'll keep an eye in case they start letting water in.
They look so much better than the stocks
I've actually ordered replacement interior bulbs as the LED ones I got originally although working are not very bright having seen what other owners on YouTube have been fitting.
