M-TECH LSMR11 – the first fully UNECE R37-homologated H11 LED retrofit

The automotive lighting market is entering a new era in the development of LED retrofit solutions. M-TECH is introducing the fully homologated H11 LED retrofit bulb (LSMR11) in a Plug&Play (All-in-One) design, approved for legal road use in compliance with UNECE Regulation R37.

This breakthrough solution marks a significant milestone for the LED replacement segment of traditional halogen bulbs. The LSMR11 has been approved for use in 12V vehicles across all member states of the United Nations Economic Commission for Europe (UNECE), allowing it to be legally used as a replacement for H11 halogen bulbs in all lighting functions utilizing this type of light source.

A fully legal LED retrofit without additional restrictions

The key advantage of the LSMR11 lies in its full compliance with UNECE R37 homologation requirements. In practice, this means that after installation, users do not need to verify vehicle compatibility lists, headlamp approval numbers, or carry any additional documentation confirming legal road use.

UNECE R37 homologation confirms compliance with strict technical and photometric requirements, including:

precise beam geometry identical to that of a traditional halogen bulb,
proper light distribution,
electromagnetic compatibility,
safe operation on public roads.

This represents a major step forward for the entire LED retrofit market and addresses the growing demand from users seeking modern, high-performance, and fully road-legal lighting solutions.

The Result of UNECE Regulatory Changes

The introduction of homologated LED retrofits became possible thanks to amendments to UNECE Regulation R37 implemented by the United Nations Economic Commission for Europe in November 2024. The updated regulation expanded its scope to include LED replacements for traditional halogen bulbs, paving the way for the legal use of modern retrofit light sources.

M-TECH is the first manufacturer to take advantage of these new homologation opportunities, introducing a product that fully complies with all current legal and technical requirements.

Premium-Class Technology

The LSMR11 is a premium-class product engineered using the highest-quality components available on the market. Its light source is a state-of-the-art 2545 CSP LED chip which, thanks to its advanced design, delivers a significantly higher luminous output compared to standard halogen bulbs.

The product also features an efficient active cooling system and an NTC sensor responsible for monitoring operating temperature. This solution effectively minimizes the risk of overheating, increases product lifespan, and ensures stable performance throughout the entire service life.

Its compact All-in-One design enables a true 1:1 installation in place of a traditional halogen bulb, without the need for additional adapters or modifications to the vehicle’s electrical system.
