ligdeun.autoH7 Adapter for Halogen Mercedes Benz H7 Holders H7 Retainers Clik Socket Base for Mercedes Benz C/B/GLA/GL/GLS Series - 402 Model Pack of 4

When my order arrived somehow the other adapter is smaller than the other one and it wouldn’t fit on the LED. Contacted the seller and got respond right away. They replaced it with new one without returning the other adapter. It fits on my 2019 GLA250. Although it was a little difficult to install it. Overall works great.

This adapter worked with some effort on my LED bulb and on my wife's car. Originally, the adapter fit on the LED bulb but was too loose. It would not seat well. I ended up super gluing the adapter ring to the bulb. I am concerned it will not last. The dust covers did close over these lamps. No resisters were necessary.Adapter ring: https://www.amazon.com/gp/product/B07R2CTC38/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1&fpw=almBulb: 25 watt each Aukee H7 LED Headlight Bulbs, 50W 6000K 10000 Lumens Extremely Bright CSP Chipshttps://smile.amazon.com/gp/product/B07FRC77GX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1&fpw=almCar: Mercedes 2017 GLE 350 with Halogen H7I would be willing to try again if I ordered the wrong model adapter, but it seemed correct, just not a great fit.

This was the closest fit I could find that would work with the low-beam halogen (not HID) projector headlights in my 2010 VW Passat, which used Hella headlamps. It did take some fiddling, bending the metal in several places in order to get a secure fit on the H7 LED lamps I was installing on the Passat. Very tight area to work in, took quite a bit of fussing around with these adapters to get a secure fit in the lamp socket.

If you use these to install Led Lights, that separate to install these between the base and light fan body, separate the collar from the Led light and mate it together with these light clamp brackets and install and clip it into the light base first, then carefully without breaking the LED bulbs mate it back into the collar and most of the have two slots opposing (180 degrees opposite) align them and then turn to straight vertical so bulbs are on the sides. It is easier to do it this way for a easier installation. I used Hikari Led Lights.

You need these for putting LED lights in Mercedes but they definitely required some grinding and sanding and I even had to JB Weld them to my new LEDs. Save some time and search for LEDs specifically designed for Mercedes. Although all of those LEDs were way more expensive so if you don't mind doing a little work but these and just about any LEDs you want.

These did not fit my 2011 Mercedes ML 350 even though the application chart said they would. I had to modify the oringinal holders to install my LED headlight bulbs. Very disappointed.

This is NOT compatible with the low beams on a 2014 Mercedes-Benz C300. There are some reviews that say they are compatible, they are NOT.

This would be perfect if it locks to the bulb, can’t blame you guys. German cars just makes everything difficult. They make beautiful cars but not DIY friendly.
