Timing Lights with advance any good?

well it's not new but it's not too greasy either lol , I bought the motor back in August as a complete package carb to pan , diz to waterpump but the water pump was the longer one and wouldn't line up with my pully's , I'm trying to get everything switched around and ready for this summer ,including a trans swap to a built 904 I put together { my first trans build } should be a fun couple of weeks . the real problem with the timing was a flat black dampener , a flat black hose and a very narrow window between everything else to see the marks , once I highlighted the mark by creating some contrasting colour down in there it turned out I could actually see about a 1/4 inch of the mark on the dampener and timing it was easy it already had about 30 total playing with it put itm too high and resetting it to @ where it had 30 left it with 32 -33 total when warmed up so bingo , now to move on to the next thing , gonna order my converter , some poly lock mounts ,a dampened torque strap , and maybe a March pully kit so I can swap to the pump Brian supplied with the passenger side outlet to match the Champion rad I bought eliminating the home made crossover hose I made and used all the way across Canada last summer lol
PS on the origional topic it sure is nice having a new light with the tach feature
