Today, I swapped out the license plate bulbs on my outlander sport with LED type. Seems the stock bulbs wouldnt last all that long probably from slamming the hatch. I noticed yesterday one died as the hatch was slammed shut. Here are the bulbs used in this post.

Because I have extra bulbs, I decided to replace the bulbs on the c max with LEDs as well. They went in as they should and work fine. The tag is a little dimmer because the LED bulbs are kinda directional or focused forward and do not radiate well to the sides. I was really surprised to see both bulb sockets blackened near the glass bulb area of the original type bulbs. Wish I had taken a pic of this but the sockets are white in color except where the bulb heat cooked em.
Here is a quick pic of of the light given off with the LED. The pic is only meant to show the brightness and that they work.

Now HERE is where the interesting observation comes in. With the car lights OFF these LEDs are still lit but with less brilliance. Because the LEDs draw such little current, they actually let me see that current is actually constantly flowing through the stock bulbs but not enough to light the bulbs. In my mind, with little doubt, the c max is losing power through the stock bulbs that we never see! Not that I have had any issues, but I sure dont want or need power being bled off while the car is doing nothing but sitting there.
Here is a pic of the light given off with all lights off.

Small update here. With the c max on its charger for about half an hour now, the led bulbs are rapidly, but dimly flashing. Much much dimmer than in the pic above where the bulbs are supposed to be off.
Should know more in next few days.
