hella 90mm headlights?

[mikes_88_supra]

just wondering if anybody could do a write up on how they did a hella 90mm install like this one.

Oooh. I like!

I second this mans motion :)

Those are not 90mm hella in that picture. If you want an accurate pic use supranick car for reference.

The problem is each person will do a completely different install. I've seen SupraNick's installation and mine will be different than his.

There's a LOT of hard work and thought in these kinds of projects and those of us that undertake these sorts of things want to be a little different. It would be different if someone wants to pay me to create a detailed document.

Projects like these are pretty straight forward if you just think your way through them. I am no professional custom headlight designer but I've figured it out - mostly.

Those lights came off a sport bike.

Please note that putting HID bulbs into a lens that was not designed for HID bulbs is illegal and will glare oncoming drivers.

i seen your post which is why i asked about the hella lights. i was wondering if you had to cut the radiator support to make the hellas work or if u have to do any rewiring of the harness other than changing the plug or do the just plug in.

and i realize that those that have done it dont want everyone to do this mod just because they want theres to be one of a kind. the reason i asked for a write up is because i have two hella 90mm halogens for the hi's and two hella 90mm hid's for the lows. i can fiqure out how to mount them and make the headlight only go up half way but i was wanting my lows to stay on when i turned on the hi's just for the added light and that i dont know how to do or if it is even posible. but if you guys dont want to disclose your secrets about that i understand.

No cutting necessary of the rad support. The wiring will need slight modification - the H4 has 3 prongs that fit directly into the stock connector. You could make a custom connector to plug into the stock connector but you really should do the rewire and use relays to drive the lights so you get the best power possible.

The linkages from the motor to the headlight will have to be shortened to allow the headlight to still go up and down correctly.

A LOT of the headlight bucket itself will need to be cut away but you will still have enough left over to maintain full functionality of the bucket while still giving yourself enough room for even the low beam Hella 90mm projector.

I suggest picking up a spare set of headlight buckets from your favorite junk yard. That way you can hack things up without worring about going back to stock.

I have the 90mm setup that you described.

For the two hella 90mm to fit, you'll have to hack up the headlight housing. You don't need to cut the radiator support. I did not do my electrical work. A good source for electrical information in this forum would be Jetjock, send him a PM.

thanks for the info glad to see some pics of a finished product.

is it the just the rod that needs to be shortend or is it the arm to?

[KeithH]

Both... because they work together. You need to change the middle pivot point (not the motor or the headlight end)

[KeithH]

Here is the best method for rewiring (Everyone should do this before thinking they need to upgrade their lighting).

Check my thread I mentioned above, I show detailed pics and info on how to modify the mechanism.

thanks for that link it was actually really helpful but i do have one question as the link talked about two different types of lighting systems. which one do we have? is ours switched by both the ground and hot side or just the hot side?

[KeithH]

I've heard that Japanese cars are typically Ground Switched. Can someone confirm - I don't have my elect manual with me at the office.

That really depends on the light fixture that you perform the HID conversion on. On non HID projector foglamps/headlamps/driving lights yes that is very accurate statement. As far as open bulb fixtures I believe it depends on where the beam is angled.

I'm very curious how you guys are passing inspection with non DOT headlights? Is one reason because our cars are pre 96(I know they use diff inspection on pre 96 due to smog testing). I believe a certain 80's year also gets a less stringent form of state inspection. In most cases, also up the inspection station AFAIK.

FYI, my headlights rise to 5/8ths of the full height just by adjusting the rod. Neither cutting of the rod nor changing the middle pivot point was required. I then used the Pivot brand "sleepy eye" controller to control how low the headlights go down when turned off.

[KeithH]

The Headlight motor was made to make a full circle (open to closed). If you only adjust the rod then your lights will only open partially. But when you turn your lights off they will only close partially. Adding a pivot controller is fine and all but I've seen those working and the light still has to travel the full path - the headlight goes up (above your standard open height) and then down.

The proper way - and a bit less expensive actually - is to modify both the rod and the arm to change the middle pivot point. That way the headlight motors can still travel the full circle.

The sleepy eye controller was designed for those people that like driving with their headlights up a bit during the day.

The Pivot controller is fine and all if that is the route you choose. It might add stress to the motor however causing premature failures if it is making the motor travel one direction and then the other.

They just don't look at the actual headlight. The Hella E-codes look like stock headlights and not the "diamond cut" ebay garbage they generally look for.

Are the hella lights already DOT? I'm going to browse their website and verify. If that's the case then shouldn't it not matter where you install them?

DOT approval is etched on the 90mm lamps.
