Headlight bulbs – what types are there and which is best?

Halogen bulbs

Although the basic technology behind halogen bulbs has been around for more than half a century, they’re still widely used, because they’re the cheapest to produce and replace.

Halogen bulbs use a tungsten filament, similar to that in a household bulb, but are filled with halogen gas, which helps the filament glow brighter and last longer. The H4 is a double-filament headlight bulb that’s typically used in small cars. The H17 and H18 bulbs are smaller, more powerful halogen bulbs, while the H8, H9 and H11 are self-sealing bulbs that don’t have to sit inside a watertight unit, so they’re often used as foglights.

W Resources Plc engages in the exploration and development of tungsten, tin, copper, and gold properties. Its flagship project is the La Parrilla tungsten project located in Spain.
