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. LED or light emitting diodes are now replacing xenons on new cars, because they are more energy efficient, last longer and allow car makers to create signature light shapes. Xenon headlights are a popular choice for luxury cars, using metals and heat gases to create a bright blue or white glow. LED bulbs are great for producing a light that is close to that of daylight and they offer less glare than other bulbs which means that they do not dazzle oncoming drivers. EXTENSIVE RANGE OF QUALITY BULBS – Simply’s extensive range of automotive light bulbs are carefully created for a long-lasting, high performance quality driving experience, range from headlight to gas discharge, auxiliary, and chrome bulbs. Your driving needs and safety are our greatest concern.

Some bulbs have only one filament, but others have two. Also known as dual filament bulbs, these are used to power both the main and dipped beam of your headlights. One filament is dedicated to each purpose. This can be easier for drivers, as you only have one headlight bulb. Cars that use single filament need one bulb for the main and another for the dipped. The addition of a blue coating to the bulb will turn the colour of the light to be more white. The downside to this is a small reduction in light intensity. We also offer a full range of OBC anti-error modules for LED kits, LED bulb-holder adapters, and waterproof covers for cars and motorcycles.There is a German national regulation for vehicle bulbs, now superseded by international ECE regulations. Bulbs according to the old German regulation are still manufactured. The German regulation is contained in §22a, Subsection 1, No. 18 of the Straßenverkehrs-Zulassungs-Ordnung (StVZO, Road Traffic Approval Regulation). Per the Fahrzeugteileverordnung (FzTV, Vehicle Parts Regulation), such light bulbs must bear an approval mark consisting of a sine wave and the letter 'K'. The technical requirements themselves are established by standards produced by DIN. Despite their similarities, each of these bulb types is slightly different. They differ in number of filaments, nominal power, and base type. While the brightness and range of the light is impressive, xenon bulbs can dazzle other drivers and create glare.

In Canada, vehicle headlamps may use light sources (bulbs) conforming to either the US or the international ECE regulations. [8] :108(5)(a) Replaceable Light Sources for Vehicle Headlamps Bulb Type Err..clearly you didn't discuss your 55 watt HID idea with him, because he would have turned red, started typing in all caps, and have called your local police department to impound your vehicle for immediate crushing. You’ll be able to spot these headlights easily on the road, thanks to their ice white/blue tint and extreme brightness. UN Regulation 99 covers gas discharge light sources for use in vehicle headlamps. All light sources acceptable under Regulation 99 are also acceptable under US regulations. There are several different classifications for car bulbs. The United Nations (UN) has set international standards for classifying car bulbs. This helps to ensure that bulb types are standard across different countries.Halogen bulbs use a tungsten filament and a mix of inert gases, usually nitrogen and argon, to create light.

The World Forum for Harmonization of Vehicle Regulations (ECE Regulations) develops and maintains international-consensus UN Regulations on light sources acceptable for use in lamps on vehicles and trailers type-approved for use in countries that recognise the UN Regulations. These include Regulation 37, [1] which contains specifications for filament lamps, and Regulation 99 and its addenda [2] [3] Light bulbs for automobiles are made in several standardized series. Bulbs used for headlamps, turn signals and brake lamps may be required to comply with international and national regulations governing the types of lamps used. Other automotive lighting applications such as auxiliary lamps or interior lighting may not be regulated, but common types are used by many automotive manufacturers.which covers light sources for high-intensity discharge headlamps. Some UN-approved bulb types [4] are also permitted by some other regulations, such as those of the United States or of Japan, though Japan has begun supplanting the former Japanese national regulations with the international UN regulations. QUARTZ GLASS UV FILTER – this bulb features a quartz glass UV filter, designed to cast a cleaner light beam from your vehicle and protect the headlight glass from damage due to direct light exposure. Xenon HID (High Intensity Discharge) bulbs are filled with Xenon gas and contain two electrodes – one on each end of the tube-like bulb. When the bulb is switched on, an electric current passes between the two electrodes and the Xenon gas lights up. The Xenon gas is actually only used during the start-up of the bulb. Once the desired temperature inside the lamp is reached, other gases inside the bulb ensure it stays lit.

These products do not have ECE approval and must not be used on public roads in any exterior application. Public roads use leads to cancellation of operating license and loss of insurance coverage. Several countries forbid sale and use of these products. You can convert your regular halogen bulb to xenon with a special kit, but these are not road legal in the UK. It's worth noting here that problems will mostly occur when switching between fittings. If you want to upgrade your bulbs, you shouldn't have any problems with any wattage or voltage change, unless you're installing an aftermarket kit. Upgrade bulbs from a reputable source such as PowerBulbs are perfectly safe to install and use.LED bulbs can be more expensive than other car bulb types, but that’s off-set with the thousands of hours of trouble-free operation you can expect. Plus, the H18 was designed as a near-direct replacement for OEMs. Thermals are discussed, briefly, in this leaflet:
