H4 has dual filament. One for high and one for low
Note: Hi-Lo beams in projectors are actuated by the the movement of the shield (that inner part which covers half the lens) in high-end projectors. Not the bulb as in conventional light reflector. Yours does not have such a mechanism, they are fixed. So you choice is either to use it as Hi (by removing the shield) or Lo (by keeping it).

I want that for High Beam, not ONLY to blind
