bout every half second for on and off. only had to replace 3 ph's in the last 6 months!

haha, j/k.
truth is it comes on for about 10 seconds, off for 5. have been using same blinker on the tank for 2.5 yrs and haven't had any problem with ph's yet. have to mention tho the hagens don't like it, sounds like a small airplane that doesn't wanna start. maxijets do fine with it.
