Automotive bulbs

Automotive bulbs are organised according to their place in the lighting system. First choose the lighting function, then compare the exact references, bases and electrical designations for the specific vehicle. If preparing a spare bulb kit, check each item separately. Data for one bulb should not be transferred to the others merely because they are for the same vehicle.

Which group to consider

For the main light sources in headlights, open headlight bulbs. For the other lighting positions, start with auxiliary lighting bulbs and clarify the exact application. This division is useful when preparing several replacements at once: make a separate line for each position instead of seeking an identical bulb for the whole vehicle. Check the data in the manual and on the existing light source.

How to compare similar designations

Record the full bulb code and cap. Then check the power supply, stated wattage and required installation dimensions. These data appear in product titles and help initial selection, but the final choice follows the exact reference's documentation. For some auxiliary items, pay particular attention to length too. For headlights, clarify the technology and required application conditions in the relevant housing.

The example does not replace checking suitability for a vehicle

OSRAM 67219CW is a LED reference for H8/H11/H16. designations. This description applies to the specific model and does not itself confirm universal physical compatibility or permission for road use. When comparing this or another LED reference, seek explicit confirmation for your headlight. The difference between a general designation and an exact application is particularly important when changing the technology used.

Checks before ordering

Compare the lamp quantity required with package contents. If you have photographs of old lamps, label which photograph belongs to which position. When comparing series in the OSRAM collection, use the same requirement list to avoid confusing different bases or power supplies. If the task also includes other car accessories, return to automotive lighting and accessories after separating lamp references. Retain the completed code list for the next replacement to start with exact product identity.
