Headings Concept (New Page) Many tags in HTML, including the Heading tags (H1,H2,H3…H6) were developed not to assist formatting but to provide information on the structural hierarchy of a document. In order to facilitate accessibility as well as standards, it is best to use the tags for the intended purpose in the information hierarchy rather

Pokud chceme porovnat H4 a H7 žárovky do auta, ty mají určitě delší životnost, než běžné halogenové žárovky typu H4 nebo H7. Cena LED žárovek je však o dost vyšší, a i jejich výměna může být náročnější. Závisí to i na designu světel daného vozidla. A teď si porovnejme samotné druhy žárovek: H4 vs H7. Z
Headings come in six levels: H1 through H6, of which headings H1, H2 and H3 are most frequently used. Headings are defined in a page's HTML. The H1 heading is often referred to as the "main heading", while H2-H6 headings are referred to as "subheadings" because they indicate sub-levels.H1LL, H1 24V LL, H3 24LL, H4LL, H4 24V LL, H7 24LL, H7LL, H11LL, H13LL, 9003LL, 9004LL, 9005LL, 9006LL, 9007LL Packaging: Individual box, blister pack Applications: Available in: 198HD, 5637HD 7510LTS, H3 24V HD H3HD, H4 24V HD Double Power: H1 24V DP, H3 24V DP, H4 24V DP, H4 24V DP, H7 24V DP, H11 24V DP Extra light output [%] * 0 50 100 150
The H1 bulb uses a P14.5 base, whilst the H3 bulb uses a PK22s base and has a wire protruding from the bottom. The way to decide whether you need a H1 or a H3 depends on which fitting your car needs. Your dipped beam and high beam will need one specific fitting of bulb and only one bulb can fit. You can't simply switch H1 for H3 and you can'tAs we can see, H4 and H7 bulbs have quite different characteristics and applications. The H4 is designed as a dual-filament halogen bulb to provide both high and low headlight beams from a single unit. In contrast, the H7 is a single-filament bulb mainly used for high beams. It has only 1 filament, but has something like a reflector built into the bulb which moves when you shift the stalk in the car and thus changes the focus from High Beam to Low Beam. No, S600BENZ, you are wrong there. In the H4 bulb, as akshay1234 has mentioned, there are two filaments : one for the high-beam, and the other for the low-beam.
