Oh I understand you yes Hid has to have a shutter so that the lightbulb is fired at all times and the only change is the shutter lifting up that way you don't have to warm up process every time you turn the light to lower or higher. I hope I've explained it right I'm sorry if I didn't let me know

I see what you are saying if you have a dimming unit. But many manufacturers just use (saving money?) fixed low beam only projectors and fixed high beam only units.

Having driven behind this set up quite a lot, I like it. You keep good illumination in the low beam pattern then add the long distance to that on high. If I converted my C5, that's the way I would go - no moving parts!

Yup that can be done and thanks for your input. I didn't want to spend way over $1000.00 for quad projectors and thought I could make something that I could happy with. My projectors cost less than $500.00 to show other people what you can do. If anyone needs help doing theirs I could help them. The best to you Gary

I really like that you are doing it your way. Were I to get enthused, first stop for me would be the nearest auto recyling operation to buy projectors.

Why 4 Bi-Xenons? Unless you already had them and decided to use them for this project, the same results could be achieved with just 2 Bi-Xenons and 2 regular high-beam projectors. It would be less expensive and simpler.

Using Bi-Xenons, there is really no need for a time-delay circuit. The only thing needed would be a Hi-4 Harness to keep both projectors on. This way switching from low to high, or vice versa, is instantaneous because the Bi-Xenon is always on at full brightness and therefore it doesn't matter that the high beam takes a couple of seconds to warm up.

That works perfectly with halogens, but with HIDs switching on the high beams wouldn't be instantaneous due to the couple of seconds of warm up time involved.

To have an equivalent result of what you describe using HIDs, you would need to do what Hotrod03 did: use 2 Bi-Xenons and 2 regular high-beam projectors plus a Hi-4 Harness. This way, going from low to high beam, or vice versa, would be instantaneous with no loss of brightness because the Bi-Xenons are never switched off. In other words, with low beam you would have 2 projectors ON throwing "low beam light", while with high beam it changes to 4 projectors ON, all of them throwing "high beam light".

I understand completely the operation of the bi xenons. My point is having a fixed low beam and a fixed hi-beam works just fine. A second or so delay on the hi's coming on is no big deal, IMO - I just prefer the coverage when the lows are always on, always plenty of close in illumination as well as long distance.

Wow thank you so much for your input. I wanted to make sure he got his
Question answered. Wonderful explanation and graphics to help others who need to know the basics. We were all there once. Once again thank you so much man, well done

Yes it's hard to see though how far out it actually throws the light out in this pic. I should take a pic on a road. I'll do that! The original lights is like a small candle compared to my hid's

Good news, working on the Lazy Eye look for my quad mod. Can't use
Set I made for my vette bc I have to change the design a little in the inside. Hope to have the finished product in two weeks!!

I chose four Moro Mini's so they would all be the same and for the small outside diameter of the shrouds to keep the headlight doors open as little as possible. In 2012 they didn't have as many choices as now and these weren't available sealed. Here's a side shot of the open position:
