for over 90 quid and comes with what they call a "ballast" that looks
like a high votage converter.

AKA Xenons.

Work well on cars that have poor headlight design. Had them on my Jag
S-Type as the non-xenon originals are almost invisible. But, without the
correct focussing lens they have a nasty scatter pattern for oncoming
vehicles.

However, they're about to crack down on them in a revision of MoT rules
so these kits are likely all about to become unpassable.
