What are the differences between LED lights from H1 to H11?

[JoelDella]

Here are the differences between LED lights from H1 to H11: 1. H1: H1 is a single-filament, single-pin type, mostly used for high beams. 2. H3: H3 is a special type, generally used in Japanese cars and rarely in other vehicles. 3. H4: H4 is a dual-filament, three-pin bulb where both low and high beams are in one bulb. The standard wattage is 55W for low beam and 60W for high beam, or 90W for low beam and 100W for high beam. Motorcycles usually use H4 bulbs with both beams at 35W or 35W for high beam and 25W for low beam. The most common combination is H1 for high beam, H7 for low beam, and H7 for fog lights, or simply a single H4 bulb.
