HB/ HC Halogen conversion.

[BigWallace]

Hi everyone! Got a pair of nos Lucas plastic bodied headlamps & now have to find the appropriate back plate & adjusters, as the original Cibie ones are different! I have converted the new lamps to take conventional H4 lamps as opposed to conversion bulbs- this allows the fitment of much brighter (but still 55/ 60W) Osram Night Breakers. The H4 inserts were taken from a scrap 1996- 2000 EK2 Honda Civic. They are held into the Honda's headlamps with two torx screws, so are easily removed. Along with these, I found some early Range Rover rubber grommets & a pair of Mk6 Fiesta sidelight bulb holders- much easier bulbs to find at the local car accessories outlets. The Honda units will fit the steel bodied Cibie lamp units too & can be held in place with three small tack welds without damaging the chrome plating. As my new lamps are plastic, they're going to be glued in place with heat & water resistant glue. Here are the photos showing how to do it. Hope this is of practical help!

Nice fit!

All nicely washed inside & out!

Lit with standard H4 bulb on high beam...

... and lit with the Osram Night Breaker, also on high beam!!

I think that doing a conversion this way is much safer, rather than the wire melting 90/140W conversion bulbs that are doing the rounds.

An excellent conversion. I did a very similar undertaking on my HC Estate but using rather expensive bespoke inserts to accomodate the halogen bulbs. I also included relays in the lighting circuit. The end result is far more efficient illumination, just for thing for my 4am journeys to work.

The Honda inserts were found purely by chance! Yes, it will make a huge difference... I remember clearly, that night driving in my Chevette at night was a total nightmare!!

Cheers,
