It isn't as simple as swapping out your halogens for LEDs. If you don't get the right LEDs, they'll burn out much faster than the halogens, or not be bright enough, not light up their housings, cause rapid flash, or interfere with the car's electrical systems.where would be a good place to go to to convert ALL the bulb numbers in the owners manual to led numbers
IIRC, there's only about an inch or so of free space behind the factory bulb. I'm also having an issue with the clearances too, as the extra connector is too big to fit in the very tiny open space next to the bulb. The 451 has a cavern surrounding its bulbs, not so much for the 453.These are the LED bulbs I plan to buy for our new 2017 smart ED when it arrives.

Neon, how much space is available at the rear of the bulb?
The rear of the Philips bulb requires room for the 1.75" heatsink.
That's a problem I already have with my 451. I think I made a thread on it back in 2012 when I first took this picture.It's a tricky thing with LED bulbs. I, too, want to modify the rear grommets to feed the wires for the LED bulbs i have (and also don't have installed) through. But for venting... i'm not sure if that's really the BEST idea. Yes, keeping LED's cool is a concern. But you'd be regretting it in the colder months. For the short time i had mine installed to test them, at one point i had to drive during a snowstorm. When i was getting closer to home, i noticed visibility was decreasing. When i got home, i realized that was because there was snow and ice building up on the headlight lens.
So long as you install the right ones, that shouldn't happen...if that's what the issue is. The LEDs may be unrelated.Perhaps you don't want to do this.... read this other forum post.
