Arnage 2007 headlight problem

[Lively Tank]

Hi Guys, I bought my Arnage T in 2018 from a dealer who didn’t seem to know very much about the car including showing me how to fold the mirrors in with a push of the hand! and hadn’t noticed it was a Mulliner 2. Anyway it was cheap and in excellent cosmetic condition but had braking and other issues which I thought might fun to fix having played with Silver Shadows for years. I then decided that I couldn’t be bothered and asked the local RRBSA specialist to overhaul the brakes etc. All done now and driving beautifully.
I have now discovered that the outer headlights have had cheap replacement bulbs bodged into them although I know why......the real replacements are.......wait for it......about £1300 each. Has anyone found a solution? Maybe an upgrade or other replacement.
Many thanks.
