Its digital and has a tach on the screen. Works mint.
I was asked to contribute money to help solve the civil unrest in Egypt, but I suspect it's some sort of pyramid scheme.

I prefer a non-adjustable. And timing tape on my car. Faster, easier. Can see whats going on without thinking about the light setting
I agree. I sold auto parts for 15 years, and my father, most of his working life. We used to collect test gear once in awhile for repair, and I've seen a number of delay lights that simply were not accurate.
Either mark the balancer--an easy afternoon job in the driveway, or use timing tape.

Use the MP timing tape. It sticks on the OD of the harmonic damper. You do hqve to clean off the surfqace so the tape willstick, but a llittle carb cleaner and you're set.
I use my Sears Craftsman dial-back light with my electronic ignitions, no problem.

Measure the circumference of the balancer and devide by 360 degrees,would probably be easier with a metric measuring tape marked in milimeters.
That's right, and not all that difficult. Start by making sure the factory mark is correct. Make a "positive stop" by putting a bolt in an old plug shell. Hacksaw the crimp off the back, drive the guts out of the plug, and braze in a bolt or tap the shell to thread one in.
Like this:

Unhook the battery!!
Pull no1 plug, and feel around with something like a plastic hanger or wire so you know you won't force the stop in on the piston.
Gently turn the crank with a socket, until the crank stops. Make a temporary mark on the wheel under TDC. Repeat going CCW. When you get done, you'll have two marks, and "true" TDC will be halfway in between. If you are lucky, the original mark will be that mark.
Now, crawl under with a small flex tape and measure around the wheel CAREFULLY. Do it twice just to make sure.
Let's say the balancer is something like 24 1/2 inches around. 24.5/360 is .0681" for each degree, or .681 for 10 degrees
Of course you can do this with metric. Do NOT use dividers or calipers. You must use a tape or flexible rule, so it "rounds" over the circumferance.
Then just scribe and file the marks right into the wheel. If you don't have a scribe, sheet rock screws are cheap
When you get done, you can carefully overlap the TDC and 10* marks on the wheel and the tab, and they should line up. You can then step up to the same deal, using the 10*/20* marks, and the 20*/30 marks, etc.
I used to mark every 10*, check them, and then use dividers to mark halfway in between, for 5* markers.
This is not absolutely accurate, but it's close enough for most of us, and it's closer than using a delay light that's out of calibration.
My health ain't all that great anymore, but I bet I can still do this not much more than a couple of hours.

As mentioned find EXACT TDC with a positive stop then mark several common marks..0632683" around the circumference is 1 degree so 38 degrees would be 2.404". I cut a piece of flexible wire to that exact length measured with a 2-3" mike & mark the balancer exactly. that being said I have a sears dial back & it's a fun toy to play with but they are based on time delay & different diameters of harmonic balancers would throw it off,how far I have no idea even if it would be close to 1 degree in a 38 degree spread but I do wonder what make of balancer are they calibrated to? MSD throws off some dialbacks but I don't have MSD so not an issue for me.
