Those housings are junk i installed that exact kit into a ford probe and it glared very badly.
As a matter of fact I have yet to see any good headlights for our cars that utilize HIDs properly.
I've played around with lots of different options as i Have 5 cars. heres how i currently have them set up and aprox costs.
Mitsubishi Eclipse- Ebay projectors that i retrofitted oem acura TSX projectors in place of the low beam. (this is the proper way of converting to HID but took about 10hours of my own labour and over 500$ in parts)
94 celica GT-4 - Im running some cheap chinese 55w 8000k retro kits (just bulbs in reflector housings) for both low beams and fogs. (light output was vastly improved but glare is horrible i feel very bad for any drivers that meet me but its not my daily driver so its rare that the others are exposed) This is the cheapest route to go as it cost me less than 80$ shipped for the 4 hid kits.
91 celica gt-4 - this car has pop up headlights so its probably the best comparasion to a 165 headlights. for this car I changed out the stock sealed beams for some hella E codes and am running some 90/100 watt h4 bulbs. In order to run the higher wattage bulbs i had to wire a relay in order to handle the extra current from the higher wattage bulbs.
91 Mr2 - stock (light output sucks)
2012 mustang- cheap 35wat hid retro kit in stock housings. Again this isnt the best option as its putting a HID bulb in a headlamp desgined for a halogen bulb it does have some glare but not enough to bother me to go through the hassle of doing a proper retro like i did for my eclipse it is significatly brighter...
Id also like to brag about my light bar that I made to bolt onto the front of my st205 that consist of 4 6" round hella driving lights with 100W hids (obviously this is not road legal in any sense but Im pretty sure you could almost tan in front of the car with a total of 620watts of HID light going in front of the car.
you really get what you pay for when it comes to lighting...
Here is a pic i took as i was changing my st185 stock bulbs and headlights out.
(left side is stock right side is hella E code with 90/100w bulb hooked up to relay harness.) Most people think its HID but it really is just a standard halogen.) The picture also shows the difference between a LHD and a RHD beam pattern. This is your best option as it maintains a proper cut off line and would be about the same price as just throwing some HID h4 bulbs in. ( i payed 140 for the pair of ecodes 12$ for the bulbs and 30$ for the relay harness and wire)
