    Rated 5 out of 5 by from Excellant Products I was a little unsure of this product at first but after I got it and tested it I fell in love with it and purchased two more. No more screwdriver in the plug wire and holding it to the block. Just pull the plug wire plug it in and turn it over and watch for the light.

    Rated 5 out of 5 by from Great Hidden Treasure I grew up using a screw driver stuck in the plug wire or removing the plug and holdling it against the side of the exhause manafold. With this tool those days are gone and no more shocks and the light can be seen no matter what the lighting is.
