What is the solution for H4 headlights not focusing light?

[LeMicah]

H4 single-installation xenon lights have the biggest issues of light scattering and slow flickering. The solution is to install a lens. The structure of H4 model headlights combines high and low beams in one reflector bowl, which has two focal points. Replacing with xenon lights makes it difficult to align both focal points simultaneously, resulting in scattered light after modification for some vehicles. Here are specific details about H4 model headlights: 1. H4 headlights are a type of automotive headlight bulb specification and model. H4 is a dual-filament, three-pin bulb with both low and high beams in one bulb, typically rated at 55W for low beam and 60W for high beam; or 90W for low beam and 100W for high beam. 2. The performance of these headlights is relatively poor. The reflector bowl is too large, causing the emitted light to scatter excessively and not focus well. If modified with xenon or LED lights, the effect is comparatively worse with severe divergence, which can dazzle oncoming vehicles.
