Vintage W German lights on 70’s Schwinn World

Hi,
Would anyone know how I can get the light bulbs out of a set of vintage lights? Specifically, a set of W German lights (pics attached) on a vintage Schwinn World Sport from the 70’s. I’m trying to determine why the bulbs stopped lighting after working on a couple of brief test rides.

My neighbor gave me the bike and I’d like to put the lights on another vintage bike.

To test, I connected the dynamo to a flashlight lightbulb and the bulb came on. Next, I’d like to see whether the bulbs blew out. However, I can’t figure out how to get the bulbs out of the housings. I remove the screw from the black plastic part behind the chrome housing. However, it won’t come off - it twists right and left only a slight bit but holds fast. I don’t want to break it.

Any advice would be appreciated. Thank you

I think you are doing the right thing, but it needs more force. I have the same lamp (Union K10709) and the black part comes out with a small anti-clockwise twist. Mine is also stiff so it is probably intentional, to prevent rattling. My dynamo also looks like yours. If is is the same model, the roller unscrews after removing the lock-nut and a drop of oil made it run more smoothly. It polished up nicely. The lamp is pretty good with a halogen bulb, but I plan to put in an LED.

Gilesa,
Thank you for your quick response! OK. Perfect. I will give it a try.

I'd suggest exploring the led conversion too.
Old school dynamo lighting was notorious for blowing bulbs.
Even low powered dynamos will power modern led bulbs.
Before I went with a modern dyno-hub, I utilised a vintage Sturmey Archer GH-6 dynohub and Edelux headlight.
Night and day performance compared to old school "globe" lighting and no blowing the bulbs.

Lots of info on the web
Google should help,,,,,, Yip I just had a squiz and there appears to be heaps like https://www.bertinclassiccycles.wordp...n-bike-lights/

Good luck

OK. Thanks I will try LED bulbs. I’ve been looking online. Going to order a pair today.

Thanks also to Gilesa. I sprayed a little WD-40 at the junction of the plastic and the chrome and let it sit overnight. It worked like a charm.
I’m attaching pictures now.
