I checked my 95 LS headlight assembly today and found 2 bulbs in main light. One for HI and one for LOW. (When you switch to HI both bulbs lit)
Is it supposed to be like that ???

What do I do if I want to replace Low with HID ?

 

Yes, that is correct. You have an H4 for low and high beams. Another bulb also lights up for high beams which is an HB3.

If you want to install an HID kit, I suggest you get it only for the low beams. Getting the low/high beams sounds nice, but I believe revving the HID's up just so you can flash your high beams could reduce the life of the bulbs.

 

Thank you for information

Nothing happens to the lamp when you swithch to or flash Hi beams. Hi/Low system works different way. It's same bulb but it has metal strip with window in it. When you switch to Hi beams small motor inside assembly moves strip to different position. You can get examples if you look on the net. Wiring not a big problem ether. You don't get twice as many wires.

The only thing that troubles me how reliable all this assembly is.

 

I'm aware of kits with that capability, however, HID's take some time to turn on. So, if you were to flash someone using the hi/lo kit you would have to wait for it to start up and by then you would probobly be on a different freeway! :P

 

I'll flash my finger.

What else can I do ?

 

I don't know if some drivers out there will take it that well.
People get killed nowadays of road-rage! Not worth it.

 

I think the lights that Vik is talking about is a single projector unit that is used for both low and high. These are like the ones used in Euro cars with BiXenon projectors. Yes, the unit needs to warm up but once you are on the road,the light is already on. "Flashing" would only involve a moving a cutoff shield up to let more light through.

 

From what I know, bi-xenons require a motor to move the bulb forward when you high beam, that requires time. I could be wrong, though.

 

I don't think so. I have a set sitting here in my office and the motor only moves the shield.

 

I see. Are they H4's?

 

You're right - motor (or something) moves the shield's window only. If you want to flash your HI's when your lamps swithed off in can be a problem because HID take some time to warm up. Caliness was 100% right when he mentioned it.

If you can't flash your Hi beams when you need it what choice do you have ?

PS:
There is an australian car sign:
"Horn broken - watch for finger " or something like it.

 

HID's are on as soon as you flip the swtich. The warmup time is the time it takes for the lamps to reach normal operating temperature and the beam color to stabilize. As for the Bixenon projectors, the movable cutoff shield is operated by a solenoid rather than a motor, which makes the operation of switching on the high beams almost instantaneous.

Another issue to consider, however, is that a 95 LS does not have clear headlight lenses. It’s hard to say, but a lens like that could scatter the light so much that there might not be much of a difference between your halogens and HIDs. This would also cause a lot of offending glare to oncoming drivers. You might want to check out www.hidforum.com for more info on HIDs in general.

 

Gotcha. Thanks for the correction.

If the Bi-Xenons are used as highs only and are usually off, then yes "flashing" would not be as effective. The point of the cars with them, though, is that they are already on as lows. When you need to "flash", the shield is moved and the light "becomes" the high beam. No warm up.

 

I would say opposite. When you flash not only cutoff shield moves to different position but another bulb lights up so you have more light coming out as well.

If I understand properly even if you have no HI beams you still must have HI's "sort of" working. What second bulb is for ? I'll check with my dealer tomorrow.

 

I don't think bulbs are separate. I think both bulbs used in Hi beams. I guess bigger bulb has 2 "light points" (? correct name) is used for Low's another used for Hi's plus smaller bulb dedicated to give higher light output when Hi's are on.
Something like:
1.1 - Low
1.2 + 2 - Hi
