Yes, they are manufactured to regular specifications. It'll be even better.
I replace all bulbs in our cars to led the moment we get the car. These days majority of the bulbs in cars are LED, but still I end up changing a few since it's not all 100% led all round.
Get proper projected leds and put them in a good projected lens with a little adjusting it'll kill the competition. HID is just a waste of energy, too bright like the sun, but very difficult to guide it in a long beam. If what you say was true, are all the engineered leds a waste? Acura and Aston Martin are going all led with Hella MAtrix system. Mercedes and Audi have been doing this since 2012.
Personally on our SUVs I've got 3000K with projectors in head lamps, and fog lamps with 4000K. In our sedans good bright 6000K in all possible locations. And I've swapped out brake lights, blinkers, parking lights, safety lights, interior lights, dashboard, instrument cluster, HVAC, glove compartment with all 6000K bright and some even projected bulbs. It's all 100% white. Only the SUV lights at 3000K look yellow but bright and powerful
6000K is amazing in dry weather. 4200K is amazing all round. 3000K is solid for penetration power in horrible weather conditions.
