If you run a true dual beam setup then your "other bulbs/ballasts" will already be 100% when you need hi beam for whatever as all that will occur will be the solenoids will activate to go hi beam. Also, the constant on/off/on/off/on/off the "other bulbs/ballasts" would be subjected to is NOT really that good on the ballasts and could very easily cause them to fail pretty quickly. The mid 2000s S-Class ran the quad setup with 4 lo beams on all the time from the factory so it is NOT like it would be a unicorn. The only change youd have to make would be splitting each side headlights lo/hi (+) feed so that it could trigger each ballast and solenoid. The easiest thing to do would be to run a dual output relay harness(1 output for each ballast) to each headlight and then use the factory lo beam wire in the OEM harness to trigger the relay to power up each ballast. Splitting the hi beam you dont need a relay as ALL it would be doing was triggering the hi beam solenoids on each projector......Just my $0.02, but i have been there, done that, and then REDONE it afterwards because it was horrible to live with in the real world........

As for the wear on the ballasts, I've found a way to program a delay for igniting the (originally halogen) spotlights, so flashing high beams will only activate the solenoids in the original projector instead of ruining the secondary projector ballasts with intermittent use.

You're definitely not wrong though, I do want to run quad low/hi constantly. I'll be doing that whenever I decide to fully upgrade to the evoxr projectors, I just don't have enough time this spring to do it all. I still need to install an LSD and replace my engine mounts, and a bunch of other stuff
