So, they work with the 4-way (flashers) on, but not turn signals?
I have brake lights and tail lamps (when headlamps are switched on)Do you have parking lights?
I only use bulbs from superbrightleds and i make sure they have resistors built in to them. I havent replaced any bulbs since swapping in 2013.
We covered that, and the SJB controls the turn signals.The hyperflashing is an indication to the driver that one or more bulbs are out (incandescent). So when you put LEDs in, the sjb thinks there is a bulb out due to less draw from LEDs.
4ways do NOT hyperflash even with bulbs burned out
The indication is either hyper-flash, or dash indicator. My VW has both...My mustang doesnt have canbus for the lights. If i have a light out i dont get a notification on the dash.
