One of my dipped headlights stopped working, twin lights style, so I swapped the bulbs around and it proved to be the bulb itself that's failed. The bulb is a sealed Wagner unit and OK one is a Philips sealed unit. I am struggling to find a replacement. Is it possible to get these or are there alternative lens units available that will take a standard bulb?
If someone could provide part numbers and sources I'd be real grateful. Many thanks in advance!

I just changed my single Euro style lights to the US twin's last year, in doing that I had to replace my low beam or dipped light as it had no parking light built in to it to meet Au standards. I simply bought a pair of these 5 3 4" H4 Hi Lo Semi SEALED Headlights Jag Jaguar XJS Triumph Stag Leyland P76 | eBay and used my H4 bulbs from my Euro style lights.

 

Thanks Katoh thts s great. I've found some similar on amazon. One questions though, does the standard socket fit directly onto the H4 bulb or do I need to order other ones?

 

I will only speak for the lights I have, I guess they are the same as yours as they came from from the US, but the electrical fittings in the rear I take that as what you mean buy the sockets should fit straight on to the H4 bulbs, Mine did as I used the US wiring harness that came with the lights, hope that helps. Just to clarify the harness that came with lights only goes between the two lights the cars harness plugs into the rear of the low beam or dipped light bulb.

 

Have you tried Autozone or similar store. They normally stock sealed beam lights

 

OK that's perfect. Bulbs and lights on order. Many thanks again.

Just saw your note, I'll look into this also. Thanks.

If you have the one piece 'euro' headlights, the harness will have a single plug that goes straight onto the H4.

If you have the twin lights, the ones that have separate bulbs and reflector units, NOT the sealed beams 'all in one' that were originally fitted to some USA cars, then you need one H4 and one H1 bulb each side. The plugs are different for each bulb type. The H4 bulb is a twin filament type that uses one filament for the dipped beams and the other for the main beams. The other unit each side (the inside lamp of the two units) has the H1 bulb and only comes on with the main beams.

Your absolutely correct Greg, just made me go back and check my old stuff. In using the H4 bulb set-up on the outer lights you will end up with with 2x high beams, What fooled me is the set I installed the low beam bulb was already twin filament even though it was a sealed lamp, meaning low/high in one but the other side was just a low, Go figure!
Anyway back to the situation at hand, you can still use the lights I recommended, simply remove the horizontal pin from the the H4 bulb so it becomes a low beam bulb only, problem solved!
Another solution is to do some calcs on using led bulbs, you maybe able to use them and keep the amps down so you can use both lights on high, mine are running both lights on high with normal bulbs, but now I will look into changing things.

 

Katoh

In high beam mode, I run high beams on both reflectors. There is no need to remove the H4 high beam pin. The system is designed to run both on high beam. That is all four reflectors are on on high beam. The H4s on their high beam mode, and the H1s on.

If you guys read OPs first post he has quad lights with sealed beams...different wire loom as H4 / H1 setup.

 

That's exactly how mine work now, just got to thinking last night after reading your post, in that configuration you have 4 bulbs on the high beam circuit, was that circuit designed to cope with that amount of amperage draw? Hence the solution to simply remove two bulbs from the equation or use 4 bulbs with a lower power needs.

That's what we are talking about the twin US style fixed beam lights.
Last year I replaced my Euro lights with twins I bought from the US, The reason I had to change my outer lights Low-beam is there was no provision for parking lights in the sealed beam light, where the US cars have parkers in the bumper the Euro cars have them in the lights. The link I gave earlier for the replacement lights have a spot for parkers in the lights and use H4 Bulbs, The wiring on the twins has simply got a piggy back harness from light to light the wiring in both cars is the same in the US and Euro cars, if that makes sense.

 

Greg
I think you have described my existing set up perfectly. Twin lights US style. In working condition, on non-full beam (dip) only outer of each twin illuminates. On full beam, all 4 lights come on.
My error condition was only one outer coming on when on dip, but all 4 worked on full beam showing that there are separate filaments in the outer lamps for dip and full.
Unit was a sealed "bulb" one piece reflector, lens and bulb.
Ordering reflector and lens units (should come tomorrow) which will take standard H4 bulbs. Hoping that the existing plug on loom will fit straight onto H4s.
Thanks to all, as always!

Read this....not a jag but sealed to H4 wire differences ....

Thanks a bunch for this. As I frequently tell my better half "its not as easy as you think", I just wish that, just once, it would be. 😮

 

That's Interesting, you might be lucky, mine just worked straight off the bat, but it was set-up for H4's originally. Still not a big problem its just a matter of switching around two terminals in the socket if it has that problem.
