Euro turn signals to US '74 connection issue

[joebarthlow]

I recently received some decent front turn signals from Germany. It has the lone spring loaded push-down wire connector. My '74 US model has two wires to to ports on the signal . I'm guessing on is a ground. How should I sent up these wires to the one hole connection Euro turn signal?

 

I don't see many relevant threads to this topic, but must be common.

The bulb in you car has dual filaments one for the marker filament and the other for the turn signal filament, both needing a feed wire.  Ground is thru the attachment screws to the fender.

Nope.  The unit is grounded through the two mounting screws.

 

One of those wires is for the running light and the other is for the turn signal.

 

Here's a thread that discusses the conversion.

lol- the trailer marker lights can be found at your nearby Walmart store.  I bought two, took them apart and modified the TS frame to attach the running light.

ahhh. makes sense now. darn US wiring! I'll go the pig tail route with the 2-wire double contact. the Advanced Auto near by has them in stock.

 

Also, are these the right bulbs? https://shop.advanceautoparts.com/p/sylvania-7528-long-life-mini-bulb-standard-performance-2-pack-7528llbp2/5080132-p?product_channel=local&store=3455&adtype=pla_with_promotion&product_channel=local&store_code=3455&&&&&gad_source=1&gclid=CjwKCAiA8NKtBhBtEiwAq5aX2D07-UjRYsfhxaFAYWtQIOVeg6UuZM5kcOKtzPFpa72-e7lOSc_xsxoCy4wQAvD_BwE&gclsrc=aw.ds

If you're using a two filament, two contact bulb for your modified front turn signal, the lower wattage filament (4 watts +/-) is for the parking light and the higher wattage (21) is for the turn signal.  Perhaps they've changed bulb numbers, but that's always been a 1157 bulb; the bulb in your post above appears to be a single filament (21 watt) bulb--what you'd use on your rear turn signals, brake lights, and backup lights.

 

Euro front turn signal assemblies are just that--turn signals only; no parking lights.  Those are built into the non-sealed beam headlights--a small (4 watt) bulb that's set in the reflector, just below the main headlight bulb.  US spec 02s were wired to use sealed beam headlights from the factory, so use either a small and large bulb (on early 02s with flat turn signals) or a single, two filament bulb on cars equipped with the "bulge" turn signals.

I used a spare 1157 in an emergency on a burnt 1156 once - you had to be careful to put the contact on the 21 not the 4

[Stevenc22]

7528 and 1157 all acceptable bulbs

 I followed Stevenc22's article and bought bulbs from Daniel Stern.  Very helpful writeup from Steven.   It works great.  Daniel recommended placing the adapter so that the side marker filament faces out.  It took a Dremel to get opening right for a nice and snug fit..

Thanks @Stevenc22 that's the route I'm going. I have all the parts now
