Timing lights !
This is a continuation from a different post where variations in timing light accuracy was a major issue. This is something not ever thought about as we ASS-U-ME that ALL timing lights are solidly accurate.
Well, I did a little researching and have found that there IS a WIDE variation in accuracies between makes, models, types of lights.
Personally I've been using my trusty old Snap-on dialed adjustable for eons and am now questioning it's accuracy. I'm looking to buy the most RELIABLY STABLE and ACCURATE Timing Light out there.
