Stick with Philips, Osram or Flosser, Hella or anything else. These cheap chinese bulbs are garbage. I replaced by D3S with Philips x-treme vision. They work very very well. Replacing with LED or lesser quality is not going to do you well.
It is clear that using the proper bulbs for the job is always the best result as the improper lighting source will always be improper. Period. LED in HID is not going to work, Lamps are not designed for LED. Functionally incorrect.
Do not fall for the marketing or pushers of bulbs, they prey on unknowing consumers. If you want better lighting, either install new Standard D3S bulbs of the same brand or again Osram, Philips, Flosser, anything made in German that is authentic. You can replace the D3S with Osram or Philips higher performance D3S bulbs.
If your headlamps are dim, never had a bulb change in over 2-3 years. Change them out and the performance will improve.
Again don't fall for cheap junk lights from China or elsewhere. Not only are you wasting your money and time but you are putting yourself and others in danger because you cannot see well and these products produce more glare on the road to oncoming drivers.
If you buy any HID bulbs, always check with manufacturer for authenticity as well. A lot of fakes out there. Do not buy off ebay. Even amazon you need to check or other vendors.
Anyway, stop buying junk bulbs that do not perform, do not fall for marketing, youtube videos or instagram photographs or anything else. Use the correct bulb from these manufacturers above.
Automotives use Philips/Osram/Hella or Flosser for a reason. If those cheaper non-name brands were any good, they's already be in your headlamps. Don't think they are using inferior products to save a buck. When it comes to safety 99% of the time they are using the best products possible.
Change bulbs every 2-3 years depending on your night driving hrs usage. If new bulbs do not do the trick, guess what, time for new headlamps as likely the projectors is corroded, the internal lens is filthy or the silver on the reflective surface is worn, burnt corroded or whatever so the performance will never get better.
I replaced both my lamps too due to not only dumb LED daytime lights no working but everything inside was dirty and I was not going to open them and clean them.
Do it RIGHT! Stay away from cheap no-name brands from China claiming High power, 6000K (which is way too high in color spectrum to see well at night), pony up for the real German brands.

These in a D3S are fantastic. Expensive but very good. Not overaly white or in blue spectrum. Still has some yellow light to be able to see well.
