Possible to have 4 low beams on GMC?

[Project1970]

Just a thought I've been kicking around for a while...does anyone make a headlight that would fit in my '70 GMC in place of the highbeams and be a combined low/high beam unit?

I know it'd involve some rewiring...but I think the extra low-beam light would be nice...basically, just have it so all four are on low normally, and then when I click the high beams on, the two go to high.

Hmm...or why not just replace all four and have all four go from low to high...

Hehe...all just thoughts, but I'd really like to know, since a LOT of my driving is at night.
