When it comes to LED lights, I'm torn between the pros and cons. The obvious pros are they're brighter, illuminate quicker, are more efficient and output very little heat. I replaced all my interior and dash lights to LEDs. Especially the console courtesy bulbs, which scorched the inside of one of the white plastic lenses. I also replaced the hood signal indicators with LEDs, but that leads to my observation of the cons.
LED arrays look cute and all, but some of those diodes will inevitably fail. Every day, I see cars with LED arrays and burnt-out diodes, and it looks like A$$. Especially cars with long taillights like 2nd-gen Chargers. And you can't just replace a handful of dead diodes, you need to buy a whole new pair of LED arrays...
very spendy. It's guaranteed to happen.
I would go for the idea of replacing the 1157 bulbs with LED bulbs instead of a full array, but LEDs typically aren't very diffuse and output more of a spot of light than a glow. I found this with some white LEDs I tried in my hood indicators; they mostly shone just a small circle of whitish light through the original amber lenses, it wasn't satisfying at all. Fortunately I found some amber LEDs that had diodes aimed more to the sides than straight out, and those made a big difference. The hood indicators now flash a nice, bright, diffuse orange color.

I'd put LED bulbs in my taillights if they made a nice diffuse glow instead of 3 separate spots of light. Has anybody tried LED bulbs that produce a wider angle of light?
