to be honest man i didnt adjust a thing, its pretty easy to do anyway but i didnt bother, i liked the light distribution, i wouldnt worry about it unless you want hids. i just got different bulbs

I already have HIDs now, I just installed them this past weekend. So I'm sure I'll be wanting to adjust them. Plus I'm on the prowl for some 3000k fog light HIDs now.

I have a '91 LS. Does it need any modifications to fit the JDM one-piece headlights?
Thanks!

not really, u need a little custom wiring harness so u can use H4 bulbs with your H3C (i think) harness.

NewLSlover

Actually...the 90-92 headlight harness are for a 9004 bulb, and the 93-94 harness is for a 9003 (h4). So, you will have to modify your harness to support that, and obviously get new bulbs.

The H3Cs are our fog lights, which you can upgrade to H3 via Lexkost tutorial.

Nonetheless, it's no MAJOR modification at all.

It's an old commute car, so I don't really need HID.
Would you let me know what I need to convert the "9004" to "H4". Thanks!

NewLSlover

You just need an h4 (9003) harness and you wire it into your current harness connection, then install the 9003 (h4) bulbs and you're golden.

Does H4 draw more power than 9004? Do I need to install a relay?
Thanks!

NewLSlover

You could install a relay, that way you wouldn't have to do as much "ghetto riggin"...and I believe h4 & 9004 draw the SAME power..but you might wanna look that up and verify.

I've seen/heard several people with 90-92's upgrade to these JDM headlights...so it CAN be done, with minimal modification.
