ooof $150 a pair lots of money but they DO look awful nice.
For now I prefer "stock" socket led bulbs. Most manufacturers are clueless when it comes to led bulbs. Morons even. LED's are HEAT sensitive. If they so much as feel more than WARM in your hand they are NOT working properly.
anything over 100' is bad for LED's that means anything over your body temperature is bad for them. They degrade quickly.
Most people think of led's as being cool but they do not realize that while LED's are insanely more efficient than Incandescents they still shunt 80% of there power into HEAT. (incans push something like 98% of there power into HEAT)
but UNLIKE incandescents LED's can not tolerate heat. typically you need 9 square centimeters of passive cooling area per watt of LED power. so a half watt LED lamp really needs about 4.5 centimeters square cooling area.
to make it works people making these fixtures like to "overdrive" led's ie put too much power into them or use CHEAP low tolerance resistors etc.. or improperly wire them in series etc..
Result? you spend oodles on an LED bulb and it does not even last as long as you incan did.
A properly designed LED bulb should Outlive your Car Outlive YOU and outlive your Children and give your Children's Children a run for there money IE 70,000 to 100,000 hours minimum.
You do NOT make LED's brighter with more power. you make them brighter by using MORE led's
in a car fixture the conditions are WORSE because now they are enclosed in a plastic insulated container making it even harder to keep them cool making properly powering them even more important.
I will eventually go all LED including the headlights if I can manage it (those will require active water cooling and no the radiator in your car is twice as hot as permitted for the led so it will have to be a seperate tiny little radiator)
Why? first they last longer. Second they use less power. A LOT less power. Less power means your alternator does not have to provide as much power which means your engine does not have to work as hard IE better fuel economy.
Your Alternator is the largest drain on your engine next to the AC compressor. Under even a normal load you would be physically incapable of spinning an alternator! its "resistance" is directly connected to the load you put on it. at 8+ watts EACH do the math. 110watts for your headlights and at least 10-12 8+watt bulbs. thats somewhere around 200 watts in lights bulbs
