running leds in tail lights/brake lights indicators rear side/guard and front

[jrudd91]

Just need some help I installed red leds in my tail lights in my vs sedan but as soon as I did when I put my brake on my dash and headlights come on... any ideas why? Appreciate it!
Also if anyone knows the globe codes for all of these would be so helpfull. Eg tail/brake light globes boot tail light globes, reverse globes, rear, side/guard and front/headlight indicators. Want to convert all these to led.
Thank you so much everyone in advance!

Don't buy cheap crap, it's wired wrong inside the globe, so when you press the brake it's feeding power back through it to the park light circuit.
You could fix it by putting 4 decent diodes in line with both park/brake globe positives but it depends on your soldering skills.

Unless you replace them with decent quality led replacement globes it'll look like crap and other drivers may not see your indicators, not to mention if it ends up like this it won't pass a roadworthy.

or you put single contact globes instead of double filament

Ok, as soon as U replace bulbs with leds U remove the load on the circuit.

U will need an electronic flasher for the indicators, otherwise it will flash really fast.
U will need to add load resistors so the circuit sees the load and everything will start working as it should. All rear brake lights will cause cruise control to not engage.

LED bulbs across the board for reverse/stop/tail isn't a good idea. Need the load of ordinary globes for the circuit.

if you put resisters on each led it might be ok
