h1's - can I run 100 watt bulbs?

Gary - did you have the correct H1 lenses in your H1 headlamps ?

The reason I ask is that because of the scarcity of RHD H1 lenses some people fit new RHD H4 lenses when they import a LHD car. These are not compatible with the H1 reflector set-up - they don't focus the beams correctly & result in greatly diminished lighting power.

If your H1's are in good condition do you want to sell them ?

Andy, how difficult are rhd H1 lenses to get? I could do with some

Andy,

Don't know about the lenses to be honest! The certainly dipped to the nearside.

Think I binned the lamps...

I'll check in the depths of the garage. What do the correct lenses look like?

The reflectors were not in great condition, although all the adjustment mechanisms etc still worked fine.

Gary, even if the H1 reflectors are shot, I'd be interested in them as a source of spares if you do find them.

H4 lenses have 'H4' embossed on them, H1 lenses are clear at the top (as opposed to a 'pebblegrain' finish on the H4's):

Looking back at some old photos they were H1, dipped right and are in the council tip in Leamington Spa. Woops.

I forget that even scrap 911 parts are worth something.

Sorry Silver7 the lenses were in good nick...

Never throw anything (early 911) away...

bringing this back to the top

what bulbs are most of you running in your H4's ?

I currently run (no pun intended) standard 55w/60w but will upgrade to something illegal at some stage. You MUST put a pair of relays into any upgrade that involves more wattage - no bad thing for standard wattages, too! Takes the load off the switch and the dip/main selector. Look for the kit produced by M Sucro (www.msucro.com ?) and glean the info - can be easily replicated with bits from Vehicle Wiring Products (or Halfords, if you must).

James - check out Ninemeister's site. They have Xenon HID conversions for H4's.
