I’m not familiar with ones that powerful. Sounds like there would be at least a heat problem. LEDs generate a lot of heat. Don’t know about a power draw issue. LED bulbs just don’t work very well in headlights not designed for them. I’ve researched them more than once for not only the smart but other makes of cars too. Every time I have come away deciding it’s just not the best idea. Why not use a set of SilverStar Ultra bulbs or another equivalent brand. I have them in my 453 as well as other vehicles and am very pleased with them.
