Ok so say I put some e-code lenses on my stock NA lights that are made for 9004 bulbs. Then I bought a quality HID kit for the 9004 base. Would this be good lighting? Also can I convert the base to H4?
This is on a mk3 Jetta btw where the e-codes have coded lenses. I know its off the wall but just something I was wondering about.

Re: E-code lights and 9004 base HID question (1984cc)

You can do it.
It's a *better* HID retrofit setup but still has it's limitations.
Here are the pros (well, the PRO):
1) Good cutoff
Here are the cons:
1) That cutoff mentioned in the "pros" tends to go up and to the right. That's meant for halogen. This means that when you overtake on the left the light goes RIGHT into the mirrors/eyes of drivers to the right and in front of you. Trust me, you'll be weary of passing ppl on the left (or when going around a right hand corner).
2) The "fluted" glass (non-clear) on those lamps mean that you CANNOT change that beam pattern mentioned in #1. It also can create just a tad bit of glare above the cutoff line (with HID's). This can also cause glare.
3) It will not look OEM. I don't know if that's the look you are going for so I'm not sure that it's a con. The only OEM's with a Fluted HID lens is the older Mercedes and even now that has gone to projector-type HID lenses. There still are many HID's in Clear Lenses though.
For your MK3 Jetta there really aren't any alternatives to this. This is the BEST available setup for your car (in terms of a Halogen to HID retrofit housing).
Using the stock N/A lenses is a bad idea. Good thing you are not doing that.
For a bit more work you can retrofit Hella Dual Rounds into your car (or the MK4-Looks) and get a better housing for HID retrofits...AGain, that's a lot of work.
Enjoy your HID's though...take good care to aim them but no matter how well you aim that upper right-hand cutoff will piss others off. I had that problem and I got sick of it real quick.
Later!

Re: E-code lights and 9004 base HID question (nater)

Yes. This is all what I figured. I love the Jetta front end and really don't want to convert to the Golf. I wonder how hard it would be to make a clear lense, like the mk4, (to make the light a free form light in a sense) then custom fit projectors in.
But say I do this and aim the lights as far down as I can, would this setup be driver friendly more then?
What about just running 9004 bulbs with the e-code lense? Would that be a big improvement?

running 9004 hid bulbs with an ecode lens will put a crapload of light out there.
And no matter how well you aim them down that right side "flare" will still exist.
You could aim them as far as they go and you'll see nothing. And that defeats the purpose.
So, it's a def upgrade.

Yeah I know it'll not get rid of the flare, you can see where its "coded" on the lenses.
Would there be any way to rebase the 9004 base on the housing to go to an H4 bulb to stay Halogen? The H4 is a much better bulb than the 9004 right?
(I really appreciate all the help by the way Nater)
