Default One JDM headlight and one EDM headlight

I've got a question about the overall beam pattern that a driver's side JDM headlight would make with a passenger's side EDM headlight... Do you guys think this would be cool, dangerous, unique, or a combination of everything? Just wanted to know what fellow driver's would think...

The patter would be something like this:

\__/

In other words, not only are you pissing off the people you are passing on the left, you are also pissing off the people that are driving opposite your direction

Stick with the EDM both sides. JDMs blind oncoming traffic, unless you want to aim them so low that they become virtually useless. VERY dangerous, any way you look at it.

i love the fact that people post stuff when they obviously dont know what they are talking about. JDM headlights do not blind oncoming traffic if you just give them a small adjustment. i have them, with an 8000k HID kit and i never get "flashed" by oncoming drivers. yes the EDM lights are the ideal choice but the JDM ones do work just fine.

Well, you have an 8000K HID kit. Not a lot of light output there, just a pretty blue/purple color. And just because you don't get flashed, doesn't mean they aren't getting blinded.

Most of the guys I've spoken to that have the JDM STi headlights say they have to aim them low so as not to blind oncoming traffic, and with 4500K HIDs (basically the color of daylight, most light output), they need to.

I have Morrettes with EDM light output, and I know, even with proper adjustments, that my light will shine on the side mirror of whoever I am passing, especially when I accellerate. The STI JDM guys I spoke to said that they have the same problem, so they have to aim the lights very low to not get hassled by cops.

Go to an area with poor ambient lighting, turn on your lights, then look at the front of your car from about 100 yards down the road, moving from one side of the road to the other, and you'll see just how high your JDM headlights shine onto oncoming traffic. Properly aimed HIDs should have a three degree drop from horizon. At 100 yards, you should not be seeing any glare from your headlights when you are to the right of your car as you face the front, with your eyes at about 3.5-4 feet (the average eye height of a driver). This is the view that oncoming traffic has of your headlights. I bet you see glare with your JDM lights "with a slight adjustment."

With JDMs, to be properly adjusted so as not to blind oncoming traffic, you have to aim your lights approximately 10-15 degree drop from horizon, which puts the most light output about ... 50 feet (?) from your car, which you outrun relatively quickly at highway speeds.

Either way, it's unsafe to use JDMs in any country where they drive on the right (as in "not left") side of the road.

I love how someone takes their one experience to be gospel .

Yeah, I figured the same thing about beaming onto oncoming traffic, but I was just wondering if it would look out of place or something. Thanks for your replies and I'll try to get them adjusted properly.

Could someone show the difference between JDM,EDM and US light patterns with somekind of simple diagram?

EDM light pattern:

each light will have this pattern: __/
there will be overlap, so the total output pattern will be __/

This is so the light falls on the road signs to the right of the road.

JDM is reversed: \__ (because their road signs are on the left side of the road).

US light pattern is usually ___ (usually there is some rounding along the top, but not much).

There's a website that lays out all the info as to various light output patterns, but I don't have it available.. I can find it again if you are interested.

Here's a real pic of the LHD projector output:



RHD would be the mirror image of this, as explained above.
