H7 Automotive LED Headlight Bulb ABS High Temperature Resistant Plastic 4.5x4.5x1.3cm 100W 9-36V IP68 for BMW 3 Series E39 520 525 Mercedes SLK 1990-2020
H7 Automotive LED Headlight Bulb 100W IP68 for BMW E39 and Mercedes SLK
This H7 automotive LED headlight bulb is a replacement bulb for selected BMW and Mercedes-Benz models, including the BMW 3 Series E39-2 520 and 525 and the Mercedes SLK. It runs on a 9-36V range and has a stated power of 100W, making it suitable for vehicles within that electrical range. The housing is made from ABS with high temperature resistant plastic, which is relevant because headlight bulbs sit in an enclosed space where heat builds up. The IP68 protection level indicates a sealed build against dust and water ingress, useful in wet weather and on dusty roads. The bulb measures 4.5 x 4.5 x 1.3cm and weighs 4.5g per piece, so it follows the compact format of a standard H7 fitting. It is listed for General Motors vehicles from 1990 to 2020 with automatic transmission, and the applicable models given are the BMW 3 Series E39-2 520/525 and Mercedes SLK.
Features and Construction
The bulb is built around an H7 fitting and uses materials chosen for the heat and moisture conditions found inside a headlight housing. The source data gives a 100W power figure and a 9-36V operating range, along with a stated service life of 100,000 hours.
Material and Build
The housing is made from ABS, a rigid plastic that holds its shape in an enclosed headlight assembly. High temperature resistant plastic is used where heat is a consideration. The bulb carries an IP68 protection level, meaning it is sealed against dust and against water ingress. The model number is D125 and the part number is D. No lampshade type is included, and no luminous flux or current values are stated in the source data.
Size and Practical Fit
The bulb measures 4.5 x 4.5 x 1.3cm and weighs 4.5g per piece. That size is consistent with an H7 fitting, so it can be checked against the existing bulb before installation. The compact dimensions also mean it fits into the space allowed by the headlight housing. The low weight per piece is another practical detail, though it should not be read as a performance claim. Only one set of measurements is provided in the source, so no other dimensions can be confirmed.
Uses and Placement
This bulb is intended for vehicle headlight replacement and is listed for specific BMW and Mercedes-Benz applications. It can also be used where an H7 fitting and a 9-36V supply are present, as long as the vehicle compatibility is checked first.
Event or Professional Use
For workshops and auto electricians, the bulb is supplied as a single replacement unit, which suits one-for-one replacement during a service or repair. The IP68 sealing and high temperature resistant plastic are relevant when a vehicle is used in wet or dusty conditions. The 100,000-hour stated service life is a manufacturer figure and is not a guarantee of actual lifespan, which depends on vehicle use and electrical conditions.
Everyday Home Use
For a private owner, the bulb is a straightforward replacement part for a BMW 3 Series E39-2 520/525 or a Mercedes SLK. It can be kept as a spare or fitted when an existing H7 bulb fails. Because the source does not give fitting instructions beyond the vehicle applications, the bulb should be installed by someone familiar with the headlight assembly, or by a qualified technician if there is any doubt.
Benefits and Buying Value
The main value of this bulb is that it combines a defined H7 fitment with a stated voltage range, a sealed IP68 build and a long stated service life. It is supplied as a single unit, which keeps the purchase simple for a one-bulb replacement.
Reuse and Low Maintenance
The IP68 protection level and the ABS housing with high temperature resistant plastic support use in conditions where dust and water are present. The stated 100,000-hour service life suggests a low replacement frequency under normal use, though this is a manufacturer figure and not a promise of performance. No cleaning or maintenance instructions are given in the source data, so only basic care should be assumed.
Why Choose This Product
This bulb is aimed at drivers of BMW 3 Series E39-2 520/525 and Mercedes SLK models who need an H7 replacement with a 9-36V range and a 100W power figure. It is also listed for General Motors vehicles from 1990 to 2020 with automatic transmission. The package contains one LED headlamp. Where the source data is silent, such as luminous flux, current and lampshade type, no claims are made here.
