I have spent the early part of the year upgrading all the lights on my SV to LED's and now just have the headlights to convert to finish this part of the restoration.
Having completed quite a bit of research, I wanted to share my experiences and get a feeling for the path that others have taken. I should caveat that I currently have original 7" headlights and am keen to stick to this size for several reasons, but not least to minimize the rewiring that comes with new 5 3/4" assemblies.
My first conclusion is that the cheap LED upgrades from Amazon and Ebay, whilst tempting are a false economy and probably illegal in the UK - a really good YouTube video here which reviews a wide range: https://www.youtube.com/watch?v=peFLmu2MfTg
So, the remaining contenders seem to be Morimoto, JW Speaker or kc-highlights; but these are simply too expensive at £800 - £1000 for the pair to upgrade.
However, I have found what I think might be a good compromise from Wipac: https://www.wipac-led.com/find-out-more. These claim to be UK legal and MOT compliant (assuming correct alignment of course). The best price I have found for these is about £400 for the pair here: https://www.paddockspares.com/catalogsearch/result/?q=s709
I would be very interested in any practical experience of these units, or any general guidance that might help with the decision?
