Oh damn, so buying a new headlight (https://lexuspartsdirect.co.uk/product/lexus-is-phase-3-n-s-headlight/?utm_source=LexusOwnersClubUK&utm_medium=ForumLinks) I need this anyway, it will not resolve the issue with the small light?
I think I will take it to my garage where I got some works done, get him to see if its a any loose wiring, if not then i will see.
Also, "But you can get non original ones cheaper if you're ok with that" Yes, I will be more than fine with that, could you point me in the direction to get non originals please, recently bought this car so struggling to find a website/scrapyard for it? Thank you
