Why no fuse for the Parking Lights?
 

Hi all, bare with me while I try to explain this dilemma. So I am wiring my 1954 frankentruck focusing just on the lights front and rear at the moment. My wife got me this really nice color wiring diagram and it confirms what was there on the truck when I got it, which is only two fuses, one for Tail Lights and the second one for Stop aka brake lights. Fair enough, good so far.

However how come the front parking lights, you know the ones below the headlights, how come they don't get a fuse?

Per the American Wire GM Style Headlight Switch YouTube video we learn that the "modern" headlight switch contains a built in breaker, but is that only for the headlights?

Logic tells me that when I add my reverse lights I will also run them through a fuse, just like the tail lights and the brake lights, but again not sure why they didn't fuse the Parking Lights.

Your comments are appreciated

so I just checked the Owner's and Driver's Manual for my 1974 GMC and what a cluster... they combine multiple completely unrelated components on one fuse, it's worse than my brothers '94 VW Corrado, ha ha

10 Amp fuse - Backing Lamp (plus cruise control?, and rear window?)

20 Amp fuse - Parking Lamp, Stop Lamp, Tail Lamp (plus Side Marker Lamp, Courtesy Lamp, Roof Marker Lamp, License Lamp, and Clearance Lamp?)

I think dash lights are on the same also

Which one?

My 68 Impala put the park/running lights on the same fuse as the dash lights. Didn't know that when I drove a 100 miles at night one time. Figured running lights were on the same fuse as the brake/turn lights which were still working.

Oh my, Yeah, I hate when they combine two or seven completely unrelated things, a fuse pops and you're like ok what blew it.

It's hard to read the diagram. Are the parking light circuit not protected by the bimetalic strip on the top of the switch?
