Turn signals

[kent olsen]

So my car 1972 911 is pretty old, right? Now the left turn signal gets loose and doesn't make a good contact. I won't go into all the little tips I tried for a better contact.

I talked to someone the other day and he said,"are you using metric bulbs?". What? Is that something available? Maybe they'd fit tighter?? Well???????

Apply solder to the lengthen the contact tips of the bulb yet?
Worked on mine.

Ken, not as weird as you think. I had a similar issue with my 2003 Z4. The rear tail light bulb kept failing. I was putting a 1157 in. I looked up the correct bulb number, 7225, and seems to be doing much better. They look identical.

FWIW, I have a similar issue with my "newer" 1973. A bit of tin foil helps.

I'll try some solder today, thanks

Are your prongs secure or do they move back with a light push?

A common issue is the tabs holding the prong base which contacts the bulb get weak or corroded. So you push the bulb in and no contact. The cure is removing assembly and drilling a 1/16” hole in tab post and base in order to safety wire prong base securely. Sounds confusing but it’ll all make sense once you get housing out.

I had the little circuit board fall out of mine. After futzing around with different repairs, I ended up getting an aftermarket bulb socket and machined the taillight casting to accept it. That was about 4 years ago. No more issues.

I think I did years ago try the solder routine but maybe I didn't put enough on them. The comment about the metric size go me to thinking because the bulb doesn't fit tight. The contacts do push in hence my thought that there really is a correct size. Wonder if the owners book or my shop manual addresses the correct bulb size, hmmm.

For the rear turn signal, the Porsche Part in the Pelican parts is # 900-631-128-90-OEM. The picture shows a 7528 of which a 1157 is the closest American equivalent.

Try to get a 7528. A well stocked Autoparts store may have one. I found the one for my BMW at Knencts.
