Actually at about 17 degrees before tdc is when the light should go out. Even if you use a real timing light you need to be able to find tdc. If you have a long reach plug like from a car of the same 14mm thread size you can screw that in until the piston hits it. Mark that position. Rotate the flywheel in the opposite direction and mark that. TDC will be exactly between the marks. Then make a mark 17 degrees before tdc. Most flywheels are almost exactly 360mm in circumference so you can use a 17mm open end wrench to arrive at the 17 degree btdc measurement.
