Sitting here bored in a hotel catching up on old threads and just saw this Henry. What you're experiencing is a quirk of the bulbs.
When I first noticed this had to take a moment to remember how the fronts were fired during hazard flasher mode. They're just left and right. So it made no sense that the fronts would go off independently when the ignition switch was turned off. Then I realized what else was going on.
Turning off the ignition switch does turn off the running lights to the front. These LEDs are energized by the feed for the running lights. The feed from the turn signal side only makes them flash. Iit turns them on and off--does not vary their intensity. They are a single intensity bulb. All bright all the time for (apparently) best visibility. The turn signal on/off/on/off makes the bulb flash by cycling the bulb off. It does not turn it on. Only the running light feed does that.
So... When the hazard lights are turned on with the ignition switch on the running lights are still turned on. So the front lights are. They flash then because the turn signal feeds (to both sides since the hazard lights are on) flash them on and off. Turn the ignition switch to off or accy, however, and the running light feed is turned off. So no more front lights.
This doesn't effect the rear as they're 1156 rather than 1157 style bulbs. No dual feeds. It's obvious what's going on once you notice how the bulbs work. With these bulbs that's the way it's going to work though. Getting hazards back in the front would require either using different bulbs or the creation of one of two new circuits. A circuit to hop the front t/s feed to the running light side when the ignition switch is off or a circuit to power the running light side when in hazard mode when the switch is off leaving the current t/s feed in place to cause it to cycle on and off.
Gawd that was terrible. Too long at the hotel bar or too much travel today. Henry might have made sense out of it only because he'd already had the bulbs in hand. Certainly not because it was written clearly
.
For anyone else that might be considering these front 1157 socketed bulbs from Ride Time let me try again.
Problem will be: When hazard flashers are engaged the fronts will only flash when the ignition switch is on. Not when the ignition switch is off or in accessory mode.
This is because: These lights are actually only a single intensity bulb. Like a single element 1156 in the rear. They're in their bright mode all the time. The running light feed turns them on. The turn signal feed actually turns them off. The turn signal feeds thus makes them blink (because they're already turned on).
The problem: You'll only have a blinking light when the running lights are on. When the ignition switch is off or in the accessory position the running lights are off. So even though there is power to the
turn signal side of the bulb the bulb is never turned on.
This won't effect the rear four-way flashers. Only the front.
Solution: Use regular old incandescent bulbs in the front. Use a true dual intensity LED in the front. Use a combination of diodes and a relay or three to change the way the circuit behaves feeding the front lights. Or just blow off the front lights when the four way flashers are on figuring that approaching traffic on your side of the road is (almost) always coming from the rear
