The Xenon Depot Xtreme Pro LEDs and DRL PWM drivers showed up yesterday. The FR-S uses PWM to make the stock DRL/high beam halogen bulbs emit a dim light in DRL mode and a much brighter light in high beam mode. LEDs don't work with PWM and they operate at full power 100% of the time when connected to a PWM system. So when you replace the stock FR-S DRL/high beam bulbs with LEDs, you are essentially driving around with your brights on all the time blinding everybody.
This kit is the only one on the market that I could find which provides the capability to use an LED for a PWM controlled dual DRL/high beam bulb and maintain proper DRL functionality. The Xenon Depot DRL PWM drivers are supposed to dim the LED light output to 12% in DRL mode and increase output to 100% for high beam mode. The kit was designed for the Toyota Tacoma, but the Xenon Depot staff told me it works for many other Toyota models. I decided to give it a chance because I would really like to match the 6300k color temperature of the Morimoto M LED 2.0 headlights as close as possible and this is only really achievable with LEDs.
Everything in the kit seems like quality parts. I installed everything on the car and the passenger side works fine, but the driver side flickers when in DRL mode. I thought maybe the LED or the PWM driver were bad on the driver side, so I swapped both setups to the opposite sides of the car. Same exact behavior with the driver side flickering in DRL mode. The LED/driver that did not work on the driver side works perfect on the passenger side.
I am going to contact Xenon Depot tomorrow and see what they say. Hopefully, they have a fix or I can just return the kit. I am starting to think I have no other option than to get some blue tinted halogens like the Philips Diamond Vision or OSRAM Cool Blue Boost if I want to try and match the 6300k Morimotos.
