DOWNFORCE –2002+ HEADLIGHT HID WIRING GUIDE
USER’S GUIDE
This is a guide created to help you how to wire the older 1991-2001 motorized headlights into the newer 2002-2005 fixed
headlights. Please refer to the proper instruction guides when installing the HID lights. If you are looking for more
conversion information, please visit our manual directory. Other related guides include:

Halogen lights run on 55 watts of continuous power. The HID lighting system runs on 35 watts. HID ballast start up requires
a higher current load of 25 AMPS for the first 5-10 seconds depending on the brand of your HID system. The factory 20
AMP fuse is sufficient to operate the HID lights, DF does not recommend increasing the fuse load. A properly connected
HID system will never blow the fuse. The factory HID on the 2002+ NSX runs on 20 AMP fuses. If your fuses are burning
out you need to check your wiring for a possible short or wiring that is too small.
• There are several WARNING sections in the installation. Always read and follow the instruction to prevent
injuries, accidents, and possible damage to the vehicle.
• Always disconnect the battery’s main terminal before performing any electrical related work to prevent accide ntal
injuries or damages.
Do not power the HID ballast without a bulb, the high voltage system will arc at the socket area and possibly

[Philips / Hella] LVQ-212 HID Ballast
The LVQ-212 ballast is a very well designed ballast with many features.
This unit is the was the result of 5 years of German R&D. The engineers
had to solve the “Hot Start” where you are turning on a hot bulb which may
explode. The ballast needs to monitor the voltage difference between a
cold start and a hot start. If the voltage is not monitored and regulated it
will decrease the life of the HID bulb. This ballast is also wired for reverse
polarity protection. There is also a safety “Shut Down” feature where in
the event there is a collision, if the ballast senses no circuit it will shut
down, to prevent arcing and possibly ignition of fuel or high voltage hazard
for rescue workers. If the LVQ-212 experiences more then 8 shut downs it
will burn out an internal fuse which is replaceable.
The Philips / Hella LVQ 212 is the most widely used HID ballast in the
aftermarket industry. Philips would sell these units as private labels, other
companies in Asia have also counterfeited this design. This unit will not
work as shown because the D2S sockets are too big to fit through the NSX
housing from the bottom hole. One fix is to modify the connectors to an
AMP plugs are supported by companies such as McCulloch, MTEC,
Xetronics, etc. This will guarantee the most amount of support in the
future for replacement ballast or bulbs.
Another highly recommended option is to purchase 2 sets of AMP
connectors and create an AMP disconnect for the D2S socket such as the
NBO system. If you have a different type of aftermarket HID system you
can always purchase a D2S socket to AMP connector so you can use
factory D2S bulbs. One place to get this is www.blinglights.com
