Unless your headlights now are a projector beam style, I would not mess around with the drop-in HID kits.

why is this?

A projector beam headlight will focus the light output as well as give it a defined cut-off so as not to blind oncoming traffic.  With a reflector beam light, you'll just be shooting ultra-bright light forward in all directions; it's annoying and unsafe for other people on the road.

I guess there are HID kits now that are made for reflector headlights; the bulbs have a black collar on them that is supposed to curtail some of the light output, but I have no FHE.

Seriously, consider wiring in relays; I guarantee that you'll be pleased with the result.  An added benefit is that you can run a hotter standard bulb since you're taking all the load away from the stock harness/switch.

Buy an old '60s car with non-halogen sealed beams. Then you'll have something to whine about.

to further expand on Staggerlee in a short direct exampled kind of way



left side is a projector style light...right side is a reflector beam headlight...

reflector beams use the "reflection" of a mirror or mirrors to redirect the light out to the roadway/surface/etc...

projector beams use a honed glass to more or less shoot the beam out in a specific spread pattern...this is done alot moreso with HID lights due to the number of lumens/output of the gas discharge bulbs...

Screw HIDs.  Get LED headlamps.  Less heat, last longer, use less energy.

Of course, I don't believe that they are as readily available yet.

Truth.

Took the 356 out for a bit tonight, since I finally got the brake lights working again. With brights going it's almost like non-bright headlights on something made in the past twenty years... Tongue

So... how do you know if you're getting the projector vs the reflectors? It looked like the ebay listings that ML posted were the projector ones. Theoretically since it's a whole headlight unit and not just a new bulb they could potentially have the correct geometry as you were talking about, yes? So then the last problem is frying the harness? How do you handle that?

I take it that the same concepts apply to motorcycles and just getting an HID bulb and dropping it into your stock bucket, yes?

Just replace you headlight lenses with some 5th order Fresnel lenses.  That should do the trick ~

So yeah, all three of the housings that the OP linked to appear to be projector beam headlights.  If you're going to to convert to HID's those would be what you'd want.  If you're not sure what you've got, compare it to the pics that zooom posted; the projector beam is on the left. 

If you're concerned with frying your headlight harness, just wire in a load reduction relay per the diagram I posted earlier.

And yes, the same concepts will apply to your motorcycle headlight as well.

My car does not have projectors in it now.

How would I know if the lights I linked to would cook the oem harness?

If they are equal or less wattage the answer is no, it will not cook the harness.  A "projector" housing does not solve the beam problem.  Every lens/reflector is designed for a bulb of a particular focal length and filament.  HIDs have a different focal length and the arc For all practical purposes) runs vertical instead of horizontal.

Have you considered auxiliary lighting?  Fogs for side coverage and driving for distance.
