Can anyone share their long term results and how their LEDs have held up? I'm very wary of purchasing any LED bulbs which aren't branded (e.g Philips, Osram). Most of the bulbs holders seem to be suitable to take a W5W LED except the vanity mirrors and mirror puddles. I previously fitted the Philips ones to my old Mercedes which I had for 4 years and they were faultless.

The kits I have seen on Ebay are:
Lightec Autostyle (seems the most genuine company)
SINCER
...the kit several users have purchased from Bond Express.
Powerful UK - not overly keen on filing down a multiplug, as it seems a bit of a bodge.

...and also just a cautionary note that depending on how generous your MOT station is, exterior driving lamps with LED bulbs fitted and are not LED fixtures are now failures (i.e numberplate lamps, reversing lights and side lights must now be incandescent bulbs as originally designed or, replaced by a complete LED fixture). 2015 Range Rover Autobiography 4.4 SDV8

My interior lights were replaced with Ebay LEDs by a previous owner - five of them are now flickering. Buy cheap, buy twice! 2011MY 4.4TDV8 Autobiography Baltic Blue

Exactly the reason I'd rather buy Philips or a kit specifically for the L322 which other forum members can recommend. 2015 Range Rover Autobiography 4.4 SDV8
