NOTE:This module works with Incandescent Lighting L.E.D. lighting or a combo of both. This module is rated at 10 Amps which will only drive 3 - 1157 bulbs. If you have a vehicle with more than three brake lights we reccomend only modulating two of these bulbs, it will be plenty attention getting enough and give you redundancy in case of some kind of failure.

• Compact, solid state electronic module converts your ordinary brake light into an attention getting visual alerting device to create more visibilty and conspicuity when you are stopped or stopping

• When BackOFF XP is installed, applying the brakes causes the brake light to emit a visual alerting signal of 4 short light flashes followed by 1 steady on light flash that lasts 3.5 seconds; the second mode emits a visual signal of 5 short light flashes followed by 1 long light flash (lasting 3.5 seconds)

• The signal automatically repeats itself as long as the brakes are applied

• The pattern is not random, it's been selected for it's ability to gain and retain the following driver's attention

• Simple installation: install in line with your brake light wire, between the brake light switch and the brake light

• Compact size: 2 1/4" L x 1 5/8" W x 5/8" H

• Sealed weather resistant heat sink case

• One year limited warranty
