That sounds complicated. I may stay with the 1156/7 original after all.
I dropped in the 4 led, single bulb version and noticed it right away in the volt guage.. I know for certian the 5w claim on 194 could be 10 ten times that given the heat.
I also heard a ticking noise coming from the distributor...the last I heard this was with an alternator change (low volts back to normal).. so whatever those little lights did changed even the runtime of distributor. I am guessing LED acts as a diode.
anyhoo... they are nice to look at...my old bulbs lit up a darn parking lot.
edit: I added upthe total watts to .144x4=.576
yes that is about half a watty for four leds.
versus the mega sucker of 20 watt minumum and hot sockets. No regrets at all..another note of change is the dash lights have a cleaner illumination.. I do not know how it did this. Same brightness..just "cleaner"
