I recently switched my parking lamp bulb, reverse light and turn signal bulb to LED bulbs and it blew my parking lamp fuse when turned on. None of the bulbs blew when turned on. The parking lamp didn't work (due to the blown fuse) but the turn signal still worked but was hyperflashing. Do I need to use a higher amp fuse or add load resistors?
Can anyone help me?

 

leds are low power so no need for a higher fuse . you will need a load resitor since leds are so low power that it maks the car think there is no bulb in the turns . You may have a short in one bulb if its blowing the fuse

 

I don't think there is a short because when I test all the bulbs they work. Also the weird thing is when I switch the 7443 LED bulb to the stock bulb everything lights up fine. So you think a load resistor for the 7443 socket will fix this problem?

 

load resistors wont fix the fuse problem just the hyperflash . Are you using a 7443 bulb in a 7440 socket ? The problem lies there if it works fine when you replace it with stock . Has to be somthing wrong with your 7443 LED bulb or the base your using with it . Maybe pins are shorting together when u push it in ?

 

No I am using a 7443 bulb with the 7443 oem socket.
If something is wrong with the LED bulb wouldn't the bulb blow too?

 

Do you have 04 headlights or 06 headlights ? 04 has 7443 3 wire socket . The 06 has a 7440 2 wire socket . If somthing is wrong causing a short in the led bulb the leds wouldnt blow because it would be shorting before it reaches the actual LEDs . Can you confirm again what socket you have and be sure the bulb is a 7443 . (7443 is also dual function hence the 3 wires )

 

I have a dual filament socket (3 wires) and I use the 7443 bulb.
If the LED bulb is 7440 would that cause the fuse to blow?
