Bud, try Walmart in the bulb section, buy a 60W standard bulb for your drop light, or get a 150W floodlamp bulb and take the shield off the drop light, but be MUCHO!!! CAREFUL if you use the big one, LOTS of heat. The 60 watt worked very well for me, just had a small flashlight in one hand and the drop light in the other, snooped until I found my problems...its like magic. But, do you need to drain the
oil after you put the dye in, or wait until your next change? Seems like you drain it, or the bottom of your car will glow for months from little leaks...LOL.
