I realize that over here in the colonies we're a bit backward in that we drive on the right side of the road but that's how it is.

The problem is that the Sera's low beam "kick up" is (naturally) on the left, which means my low (dip) beam dazzles oncoming drivers. I'd like to reverse the beam pattern so the kick up is on the right. This might just be a simple matter of locating and reversing a mask inside the projector unit. Has anyone had the low beam projector units apart? Any opinions on whether what I want to do can be done?

Info copied from email sent to me in March 2002

Hello Andrew,

I.. Headlights, it basically it comes down to what I thought:

a ) Disassemble the light (heat to 40-60 C) assembly. Instructions HERE

b ) The lens of the light itself is not directional, it's the metal mask between the H3C bulb and the lens. There is a triangle to create the specific beam pattern. You simply have to remove the unit, disassemble and cut the triangle on the other side and use the cut white metal piece or aluminum and epoxy this on the other side (otherwise you have dual side dipped beams). Axel did this on one side already. Being precise on the gluing and grinding of the mask is the other critical part. Good Araldite epoxy will handle the heat & vibration. (see photos below)

c ) Re-assemble using heat & the special Loctite glue for headlamp assembly.

Headlamps dip one way or another to prevent you dazzling on coming traffic too much and to light the kerb slightly better. Park up against a wall at night and see.

Canada drives on the wrong side of the road to Japan, the UK and Australia, so they have to modify their headlamps.

Thanks for that, Andrew. It is as simple as I thought (except for the bit about aligning the masks).

Only problem in British Columbia Canada, the headlight has to be stamped DOT or SAE or they won't pass it, even if you reversed the beam pattern.

I live in alberta and what my friend and I did was go to a junk yard and get some light baskets and then a couple headlights that match and are canadian ( dot) and fit them in took about 2 hrs if I remember right. Good luck and keep trying you can make it work

Sounds like a Canadian requirement. Interesting. Guess all the Skylines pouring into Canada have to do the same thing? Might be a screw adjustment for them. The Sera is unique in many ways, headlights being one of them.

Good mod to know if you have to do it.

Firewarden,
 
I realize this is an old post, but could you possibly swap in a similar headlight? Like from a 1st gen Previa.

I'm not sure about the dimensions, and I'm sure it would take a little body work, but they look similar in size.

That would at least give you the DOT stamp.
