I put in about 4 hours of time aligning my headlights according to Daniel Stern's fancy instructions. I kept aligning until I got the horizontal and vertical adjustments just right. There is no doubt that the lights are bright especially with phillips hir bulbs but the lights seem to emit strange patterns all over the road and even more strange patterns to the left and right. Just wanted to see if anyone has noticed a very different beam pattern with their 93 lights.

Thanks

Ah I missed that because you typed 'hir'. I thought that was a model of bulb. Yes, it has nothing to do with the '93 headligts other than the fact that they were designed for 'normal' halogen type bulbs. HIDs MUST be housed in proper projector housings or you will get that strange spread of light and cut off that you are talking about. It is also worth noting that the patterns you see on the ground are only the light that is being thrown downwards. There is going to be a fair amount of light that is going to be thrown up and to the sides as well, which is actually really distracting (and even dangerous) to the drivers of oncoming traffic.

You can retrofit projector housings into the '93 lights but it is time consuming and expensive. The cheapest way to get a decent spread pattern is to replace your HIDs in the headlights with stock halogen bulbs (a slightly higher wattage works well if you want more light). Then you can relocate your HIDs to something like the USDM/JDM projector foglights and wire them up as driving lights.

Well in that case, the bulbs were still not designed for the housings. Normal halogen bulbs create no noticable weird patterns or cuttoffs.

It might if you can get a photo to show the patterns, it isn't always easy. But putting stock bulbs in might also help for diagnostic purposes because if they produce the same patterns then you know it is the housings doing it. Is there any cracking or peeling of the reflectors in the '93 housings?

Sorry thought you were using HIDS

No problem, I know that it hasn't really been discussed much here, but outside of this forum it has been intensely discussed.
