Chris shows how to refresh and repurpose some TIR6 LED lights.

http://sirennet.com/wh50--3zcr.html This is the Split Version of the 500 Series TIR6 Super-LED Lighthead. They offer the same compact size and super bright light output as the standard TIR6, plus the additional attention getting action of a split lighthead. This compact lighthead is perfect for mounting in the grill, on side mirrors, on bumpers, or numerous other applications. The TIR6 uses Generation 3 LED's and over-sized reflectors with spreader optic lenses to fill the entire lighthead. Whelen's SmartLED design alternately or simultaneously flashes each color segment (3 x 3) in any of the Scan-Lock Flash Patterns in Phase 1 & Phase 2. The TIR6 has a Scan-Lock flash pattern wire to change between built in flash patterns. This four wire TIR6 includes the synchronization interconnect wire that allows up to eight lightheads to be synchronized together. All TIR6's come with clear outer lenses - the color is generated by the LED's. Features: Wide Angle Generation 3 LED's with spreader optic lenses. Scan-Lock flash patterns with Phase 1 and Phase 2. Can be used in either solid or split modes. Includes synchronization feature wire. Epoxy coated for vibration and moisture resistance. Designed for Horizontal Mounting. Dimensions: 5" W x 1-5/8" H.
