How I changed the beam patern on JDM proj, idea taken from Jason :) Options

[Culpable04]

to change the beam patern of the JDM projector we need to change the shape of a metal piece inside the projector.

that piece looks like this on the stock form


and you want it to look like this



the red color is what we're gonna installed now so the beam patern will be a straight line


Materials used


aluminum foil
small tweezers
crazy glue or equivalent
patience ( lots of these will be needed )


1- open the back of the projector, removing the bulb cover and bulb


2- make a "L" shape piece with the aluminum foil thing enough to pass by the opening on the back of the projector but as thick as possible ( don't make it snug fit need to leave room to insert the aluminum "L" without touching the side of the opening )



3- apply glue to the base of the "L" and pass it through the opening, for this step you need someone holding a flashing or light source from the other side so you can see the metal plate with which you're gonna align the aluminum "L" also try to practice this step a few times without the glue so if the piece falls off no damaged will be done.





when you're done you should have something like this




I hope this helps a few and to me was a better idea than opening the whole housing.

Thanks a lot Jason for the idea.

haha for all who havent had projectors, its normally supposed to just be a flooding sheet of light in front of the car that abruptly cuts off a bit below the vertical horizon in front of your car, the idea is to provide maximum lighting in front of your car while reducing glare to other drivers - allowing you to put in much brighter bulbs while note blinding anyone. on jdm projectors the cut up severely to the left, glaring off of directional signs on highways, tops of houses etc and blinds the hell outta oncoming traffic. since they drive on the other side of the road over there, the lights do a great job at lighting up the road given that oncoming traffic is on your right there, not on the left like in the states. i for one do not feel comfortable removing the lens of my nice projectors that dont leak or fog up so i decided to do something like this, yes its kinda ghetto, imo its straight forward, no more a pain in the ass the changing any interior lighting (gauges, cc unit) and is very simple, as culp will say once you do one projector, the other one is a million times as easy

when i did mine, i kinda rolled the foil a bit to fit through the hole a little better, then just poked it with tweezers then bent the top part back to form the straight line you want, since doing mine earlier in the week, the glue i used (just hot glue for ease of application) has given way so im going to try using something different and probably more of it since i only used a spot on each

good job culp and what kinda adhesive did you use? i was contemplating using a few cut pieces of duct tape because of its opacity and it sticks well - like cut 3 small pieces instead of one big one so it fits in there and you can line everything up better.
