So I’m wondering if there’s any trick needed to properly replace all the conventional bulbs with LEDs in these cars? Ive managed to get a few LEDs in my ‘85 P-type working, one in the door courtesy light, one in the map light, and a couple in the instrument cluster. But if I try to add another like in the hatch door light, it’ll blow the dome circuit fuse. So I’m guessing the LEDs are allowing the current to build and surpass the fuse rating.

So is there anyone who has figured out a solution to this or maybe found larger/brighter conventional bulbs for the interior? I’m just finding the stock bulbs are too dim, even for night use.

Generally, LED's draw less current than regular bulbs...
Wondering if the socket has issue with your LED, and making a short with it.

That’s the understanding I’ve had too. I also know that the LEDs are single polarity, only working one way. I always check if I can that I have the polarity right before fully installing the LED.

Probably a bad bulb with a short in it. I only have done one in my car and that was the overhead light on the sunroof control panel. I bought one of these and put it in there;

It lights the car up like daylight inside.

I’ll have to pick up a pack of them and try. You can probably imagine my confusion when I just got the hatch light converted with the driver door courtesy light and map light on the sunroof control panel all working, shut the doors, and as soon I open the driver door, fuse pops. Put the conventional bulb back into the hatch and replaced the fuse, everything is fine. I may have to check all the sockets and grounds for fraying or maybe corrosion. Just find it odd that the courtesy/dome light circuits won’t accept more than two LEDs.

I’ve got a similar LED board in the map light by the sunroof controls. Insanely bright. Sure would be nice if that light was set to come with the doors like the dome is.
