Inside some 10W LED jeep or truck lights.04:33

I got these mainly because I really liked the style of the aluminium housing. They are basically a housing with an LED, driver and glass lens on the front. They actually run the 10W LED at 4W, which is probably a good thing, since the quality of the LEDs in the chip are poor.
It also has a hazard mode where it strobes the lights in bursts.
The driver chip is PT4115 which is more than capable of driving the LEDs at their proper current, but is set to the lower current, possibly because of the LED quality or the limited cooling area.
The driver chip has an enable or PWM input which is used for the strobe effect in conjunction with what is possibly a generic PIC 12 clone.
The lights come with adjustable pan/tilt brackets, and also have two threaded holes on the back to accept the supplied studs for bulkhead mounting.
The light output is quite a nice lensed beam. These lights are very hackable.
