Headlights ... Early Late to Late Late..

Discussion in 'Mech Tech' started by Deefer66, May 25, 2020.

  1. Just to raise this subject again..

    To enliven lighting I swapped out the tired old Hella separate glass and bowl unit for a repro mk1 golf sealed unit as is popular. H4 fitting. see where your going etc...

    But with the 3 hole rims theres only one tab on the bus and that's no use for fixing the lamp.

    I've gone Heath Robinson, drilling new holes in the lamp surround fixing the lamp to the rim with nylocks using the old adjusting screws..but his makes adjusting a pain..

    Is the only other option fixing tabs in the bowl..as it would make adjusting easier .. or am I missing something?

  2. Nutserts and rubber behind chrome bezel maybe. Have just removed our bowl if you want pics of fixings or can cut them out and send them bud...[​IMG]

    Or you could get new H4 reflectors for your old rims and lenses.

    I thought that sealed beam units were something that halogen bulbs had put paid to by about 1980, as the halogen chemical cycle needs small hot quartz bulbs, while sealed beam are just big light bulbs, so you cant get the light output before they burn out compared with halogen.

    Replacing H4 round bulbs with H4 halogen bulbs is simplest in original reflectors, and for freshening up reflectors, Golf Mk1 units with halogen H4 bulbs.

    The glass is stuck to the bowl on lights using a high temperature glue, melts around 200C. I have managed to bake off the glass on a cracked foglamp in a domestic oven and swap it for glass from a rusted reflector.

    New reflectors in your old lights would have been my choice though they were £40 each when I bought a pair 20 years ago.

  8. It is an option I'm considering in trying to get the reflectors off the new ones and onto the back of the Hellas...my method not so good on passenger side lamp, will end up cross eyed.. replacement reflectors look hard to come by at reasonable cost..if only chrome spray looked like chrome .. without the re-chroming cost...

    Why not just fit them As they were fitted from the factory on late bays

    The headlight holder fixes to 3 tabs in the headlight bowl, the chrome bezel fixes with one screw and adjust the headlight with the adjusters on the holder

    easy peasy
     
  10. Not when you only have one tab in the bowl.. just need to pick between adding tabs to bowl v moving reflector to a one tab headlight..

    Think the adding tabs might be the easier long term option..

  11. So as early reflectors are about £80 a pop , whole 3 screw units an out £110 a side, bowl transfer would be a pain each time a lens gets cracked ( not offer but sods law!)

    New tabs seem the way to go..

    Looking at Lola after the spray (blue)

    I'll need 3 extra tabs

    The rim holding one has an extra hole above on one side and below on the other (photos on wrong side above!)

    Is it easier to fix a tab and drill /tap in place to get hole right?..

  12. Found this and shamelessly stolen from Earlybay post by “reezvaan", in case anyone else needs to know where the extra brackets go for the extra three tabs..link below bit I think it's members only so content copied too..

    it wasn’t continued on the thread I found but pretty much there for fixing purposes.
