Default Re: Red Light Answer

Maybe far fetched but food for thought. Has this problem only surfaced since the beginning of LED prestage and stage lights. Regular bulbs have a filament that that takes time to cool off and can be relit and not not be noticed by the human eye. Not so with a LED . much faster on/off. Example - LED brake lights and why they use them today. Could be a tie in with the electronics ?

The one that happened 2 years ago was the old style stage lights.

The Defrank car has smaller tires on the front. And the way these cars are built today they sit very low to the ground so the pre-stage and staging beam have to be fairly low so the front end does not trip it. (not sure what the standard height is). With that in mind when shallow staging there is less circumference of the tire blocking the beam. When setting the trans brake most feel that your car won't and can't move. When staging you set the trans brake, during that time you are waiting to release the button. If that car with small tire moves .030 or .050 or .100 for what ever reason, more back up pressure applied than forward, wind, etc ... do you think anyone would be able to actually see that movement, but that may be all it takes to light the red light by allowing enough of the beam to make contact to the outside cell.

So what you have is a 900 hp car that is relying on a trans brake to keep it from moving in either direction ..

just a crazy thought ...
