Highs and lows at the same time?

[Eliot_Ness_Ls]

I was looking through the search and couldnt find anything but I see people with the highs and lows both on. How is it done if I may ask?

 

[SoonerLS]

All 2nd Gen LSes keep the lows on with the high beams, probably to simplify the logic for the HID low beams, which need to stay on because of their longer start-up time relative to halogens. 1st Gen LSes can do it with relays (IIRC, Rebel posted a quick and dirty schematic to do it late last year).

Do you think a second gen headlight retrofitted to a 1st gen harness would do the trick?

I'm pretty sure the answer is no; the difference is in the FEM (or maybe the wiring harness), not the headlight assembly. You'd just wind up different sized lamps that alternate being on.

 

[Eliot_Ness_Ls]

Can this be done somehow or a another with a non LSe? Can the wires be spliced together ( in a profesional way) somehow.

Rich Thompson at mn12 used to sell a kit for what you speak, but then he sold out to Supercoupe Performance. And since I don't like Bill Evanoff, I'm not recommending you buy from him.

Here is the contact info for the people who made the harness (mn12 just resold it).

I've had one of their setups on my old Supercoupe and on my 97 1/2 ton Chebby, never had any problems with them. If anything, the harnesses kept blowing Sylvania Silverstars because it allowed them to work at their full potential... something that I'm sure Sylvania planned into the design, and accounted for power drops across the whole OEM lighting circuits.

If push comes to shove, i know a guy that might be interested in making you a harness.

Sorry I ment to say "second gen headlight HARNESS retrofitted to a 1st gen headlight".(sorry long A$$ day) but I think you answered my question anway.

If I'm reading you correctly, I don't think that would work, because you'd wind up running both sets of lights off the same circuit, which would certainly overload it. Relays will do the job without setting your engine compartment ablaze.

IIRC, there's a topic about someone (ovsims?) installing 2nd Gen HIDs in a 2000 LS. You might look there, but I don't think he ever did anything about not having the lows and highs on at the same time.

Should be able to do that with a standard 5 pin relay.

85 - high beam signal
86 - ground
30 - to lowbeam lightbulb
87a - lowbeam signal
87 - +12v fused. Could connect high beam signal here but it would probably blow the high beam fuse.

(i haven't tried the above... just thinking...)

I believe it is wired this way for a DOT standard. IIANM - you are only allowed four forward facing bulbs on at once.

so -
- first gens - can have their fog lights on and either the low or highs
- second gens - can either have lows and fogs or low and highs - but the fog lights turn off if the highs are on

someone with a second gen confirm...

 

[Eliot_Ness_Ls]

I might be missunderstanding but, my highs dont go on with my fogs. When I turn on my highs my fogs go off and I drive a 2000.

 

[SoonerLS]

On 2nd Gen LSes, you have fogs with lows; when the highs go on, the fogs go off. The lows stay on when the highs go on. (At least that's how my '04 worked and my '06 works.)

you're right - I justed test the flash-to-pass and they stay on - but if you turn on the highs - the fogs go off.....

+1 the fog lights turn off when the high beams are put on. the last thing you want in a thick fog is your high beams on.

 

[gt95coupe]

I thought we were talking about the low beams and the high beams at the same time not the fogs. Ive got an 2002 w aftermarket HIDs in my lows and dont want to cycle off the lows every time I want the highs on or to flash the highs

 

[Frogman]

Sure you are. You can have Low beams and fog lights on at the same time, no?

I know what you mean though, Quick.

On my powerstroke, the Figs stay on with the Highs (yes, I wired them that way). And once I get the cow catcher installed, I will have an additional three 5" High output lights mounted on the grill, and four high output lights mounted into the cow catcher. You can never have too much light.

 

[owlman]

I wonder why the lows go off in the first-gens then, if not for the fogs.

 

[beaups]

Every car I've ever driven turn off the lows when the highs are on...except my 03 LS w/HIDS (and the reason has been covered here).

At any rate, it you want the lows to stay on w/the highs you need to wire in a relay or two, no biggie.

I always thought lows went off with highs was

1.) power (lows and highs combined will pull a lot of current)
2.) focus - when you turn your highs on you can see further. With the lows blasting still at a different angle but much brighter near the car your eyes seem to compensate (closing your iris) effectively negating the effect of having the highs on

Just my theories.

b/c the lows were not HIDs. My g/f 05 avalon keeps the lows on when her highs are on factory HID

This is the pattern I see, its cause they arent HID's.

Frogman ...LOL WTF is a cow catcher?

 

[Frogman]

Cow Catcher.

I think the more civilized people call them "Grille Guards".

 

[owlman]

Yeah but non-HID 03+ have the same behavior.

Cow catcher... LOL
I've never heard that for truck grills, only that thing on the front of locomotives. It's a good term

 

[beaups]

Yeah but non-HID 03+ have the same behavior

probably just to simplify the wiring process and not require different switches and/or modules for hid vs non-hid models.

 

[Eliot_Ness_Ls]

HAHA...cow catcher, I had a crash guard on my Fury 3. I never heard it called a cow catcher tho.
