Anyone know anything about these? Adjustable voltage regulator P/n 2098300. Supposedly a dealer fix for dimming headlights on 61-69 mopars. Does it do anything?

I dont know about that.But just get the new style that is plug and play for OE.Its electronic and unless you have electrical problems they work great.Had them installed on 4 early cars and no problems.rocky

I remem seeing a pic of one of those decades ago. if it functioned I'd like to have/try one to play w ch voltage a bit & I've thought about using a variable resistor of some sort just to do some experimenting but I dont have enough electronic savvy to pull it off. You have one? I was thinking it had a little screwdriver slot flush w the case

that's it. What Therocks said, the stock electronic works pretty good. IF all terminals/connections have minimal resistance & I like a better alt/relays on the heavy draws. On the older setup an electronic version is highly recommended
