The restoration of the lighting for the Mach 1 has in my restoration focus from the beginning. Since I had most of the original lighting pieces and they are relatively simple, they bubbled up to the top of my to do list quite often. The Parking Lamps / Turn Signals were the ones that I most recently completed.
As I often do, I started by assessing the original parts. As shown below, I had both original assemblies. These included the housings (comprised of housing, socket, and wiring pigtail), lenses, and gaskets (though these were crumbled and basically gone). A few minutes in the sandblaster let me assess their condition without any rust/dirt.




Blasting the housings showed that there was rust/rot in the area where the housings are spot welded together. Based on the location and assessment of my welding skills, I decided not to try and repair these. A pair of new assemblies was purchased. I got a pair for $90 + tax + free shipping off of eBay. These came in as shown below, in Dynacorn branded boxes. A quick search on RockAuto also showed these being sold by GoodMark (GOODMARK GMK302207170LS, GMK302207170RS). They are also sold through CJ Pony Parts, with the wiring looking a bit more original.



The lenses they come with are unmarked. As I still had my original lenses (which have the Ford oval logo) and they were not cracked, I opted to use my original lenses in these new housings.



On the left is the original lens (lower) compared with the new one (upper).
Before putting the assemblies together, I used Novus plastic polish to clean up the lenses. It won’t take out deep pits or scratches but will clean up the fine ones. The lens get hazy during the initial polishing and then clean up as you move onto the next polishing step.

The lenses were then bolted to the new housings with the included hardware. The gaskets, which appeared the same as the repros I could buy, were reused. I didn’t love the look of the wiring, so decided I would add some looming to protect it and clean up the look a bit. At the time I didn’t realize that there were two versions of this light and looking back likely would have just bought the other version.


I used 1/4″ Taylor loom and Berry Polyken tape to secure the loom around the wiring. Loom was cut to the correct length and slid over the wiring. I think they came out okay; not 100% original but I am okay with that. It was nice to reuse the original lenses. If I had to do it again I would have purchased the ones with the more correct wiring….but now YOU know.
