plumster Posted March 31, 2020 Share Posted March 31, 2020 Shame they are just the lenses, its the reflector part that gets knackered. Quote Link to comment Share on other sites More sharing options...
Monaco Blue Posted April 1, 2020 Share Posted April 1, 2020 The other side is a Tenner cheaper! https://www.ebay.co.uk/itm/Vauxhall-Cavalier-MK1-Opel-Manta-B/254470809019?hash=item3b3fa465bb:g:CqwAAOSwTs9eD1Br They look more like later headlamps than early, but stand to be corrected. 1 Quote Link to comment Share on other sites More sharing options...
BIG STU Posted April 1, 2020 Share Posted April 1, 2020 Hi everyone. Hope you are safe and well. These headlights aren't for the early b that has the eye brow surround on them. Gutted as I would of had them both as spares. O well.... 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted April 1, 2020 Share Posted April 1, 2020 yes definately later type. early ones had the surround like you said.then the style after had a more flat fronted glass up to around 78 ish.these are the next type H4 halogen.quite expensive thou but i suppose they are getting rarer now ! as you say its the reflectors that wear out first ,followed by glue failure causing internal condensation. 1 Quote Link to comment Share on other sites More sharing options...
markyb0y Posted April 21, 2020 Share Posted April 21, 2020 Is there a problem using later lights on an earlier model? Or is it just to keep them period correct? My '76 cav had globe style, non halogen bulbs when I first got it which I swapped for halogen units from bro' s manta GT/J - 1x lucas, 1x, Hella. I hadn't noticed any difference, but I have a spare lucas lens to switch with the hella to make them match if it's worth the effort? I'm not sure if I have the originals any more. The lenses were OK but the reflectors were shot. Would you suggest swapping the lenses back if I can find them? Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted April 21, 2020 Share Posted April 21, 2020 nothing wrong with fitting later h4 units to earlier models physically or electrically.just straight swap .and shouldnt be anything wrong with it legaly either as they will have the correct beam pattern. thats where swapping reflectors or lenses can be an issue ? the early cars had the same reflectors but i beleive the bulb sheiding was different .also if i remember correctly the actual non halogen bulbs were a different actual fitting .and non h4 lenses MAY have different pattern ?? some later cars had lucas units but in all my experience of these the reflectors didnt last long (painted plastic rather than chromed metal) Quote Link to comment Share on other sites More sharing options...

markyb0y Posted April 21, 2020 Share Posted April 21, 2020 Thank you, that makes sense. The non halogens were like candles and I needed to hold a torch out of the window to see where I was going! I'm guessing the beam pattern is OK as it passed its MOT with them fitted. Its probably more important to have useable headlights and forego the period features. So the hella units are the best, until they rust, then use the Lucus with Leds? The lucas ones always seem more expensive and I assumed they were the best.
