At least early 60's, uncle had a Buick with most options, if not all I would guess. About 62 or 63, at the latest 64 he drove up to my grandparent home and did not turn the lights off. Somebody made a comment, and he was letting everybody know he had the fanciest car so they would turn off automatically. And yes they did go off by themselves. But had to add they dimmed themselves too. In the middle of the dash was post 4 to 6 inches high with "eye" on the top. Quote Link to comment Share on other sites More sharing options...

I have never actually seen published anything on reflectivity with relationship to kelvin rating. Back in the day I got some fancy fog lights which were extremely yellow, which would be low in the Kelvin scale, I couldn’t be sure but I would say sub 1,000. In my house I have track on each side of a room, one side is log wall, the other side painted sheet rock. I went with 4100K bulbs against the logs and 3000K against the sheet rock, it seems to balance in terms of even lighting and appearance. The darker surface seems to reflect more with a higher K rating even though the bulb produces the same lumen output. as i say, I have no chart or graph for this, but I have been experimenting. It makes sense then to me that the lower your K rating the less reflection in fog you would get. Quote Link to comment Share on other sites More sharing options...

And it obviously ain't me😄 I was thinking it was a company I used to procure lighting for our firetrucks. Looked through my list last night but came up empty. The only thing I remember is thinking, "this is a chart I need to save"................................ Quote Link to comment Share on other sites More sharing options...
ihrondiesel Posted February 2 Share Posted February 2 JWSpeaker headlights on my truck. $295 apiece and I have 4 of them. Money well spent, you won’t regret it. Yours will be cheaper, @sandhiller, since you only have one per side. Although the per light price may be a little more. Driving in fog sucks enough without worrying about your headlights frosting over! 1 1 Quote Link to comment Share on other sites More sharing options...

wild one Posted February 2 Share Posted February 2 I took our 2018 in for service on day. they sent me home with a new 150 with all the bells and whistles. It was a foggy rainy night and with the automatic dimmers an wipers and those halogen lights or whatever they were was the worst vehicle I ever drove in fog. I have never tried this ,but a friend carries a roll of duct tape in his truck and tapes off the top half of headlights in fog. Swears he can see much better. 1 Quote Link to comment Share on other sites More sharing options...

Rawleigh99 Posted February 2 Share Posted February 2 My father had a 1969 Lincoln that had self dimming lights. It had a little pod mounted on the driver side in front of the A pillar that looked like ET's head. It was a collar around the base of the light switch that adjusted the sensitivity. I don't recall it working very well though ! 1 Quote Link to comment Share on other sites More sharing options...

Maybe if he just taped over the top half of his eyes? It would save getting out in the weather? 1 Quote Link to comment Share on other sites More sharing options...
jeeper61 Posted February 3 Share Posted February 3 Since the chart guy didn't show If I read this correctly this is a fog light pattern on a ICE powered vehicle A EV light would have a shorter range 1 Quote Link to comment Share on other sites More sharing options...

Introduced in early '50s on Cadillac and expanded to Olds and Buick, it used vacuum tubes in the amplifier the photo cell controlled and the tubes eventually burned out causing them to fail. They really needed more advance electronics. I've driven a couple of rentals with it and while it works I normally will dim way before it will and it doesn't consider trucks where the driver gets hit because their lights are mounted low and they sit high. 1 Quote Link to comment Share on other sites More sharing options...
