Bought a retrofit projector kit which will be fitted in OEM Volvo headlights for my S80. This will ensure that using HIDs or LED will not blind other drivers. The projector kit was sourced from Aliexpress. They are bixenon, but you can just snip off the wires as this functionality is not needed in the S80. The high beams are a separate H7 bulb.
Highly recommended, fitting them is quite easy. There is no butyl or permaseal used on these headlights. Only a small number of metal clips are used to gain access to the headlight internals.
I bundled them with H1 Led units, there give a tremendous amount of light without disturbing other road users.
The images should speak for themselves. If not, leave a comment!
Snip away some of the material as shown.
The end result looks good, very happy with the results
