Included among Superior Signals' (SSI) LED snow plow light collection is the LED04 Series.
When used together, the LED04 series will provide complete coverage of a snow plow blade. With six LEDS and 15 flash patterns, the driver and surrounding traffic will know exactly where the blade is at all times. The horizontal set will show the exact position of the blade when it is down and in use, while the vertical pair indicates blade position while stored in the travel position. These lights are encased to resist vibration from the blade running along the road, as well as corrosion from water, salt, and chemicals.
