This bulb is a single element bulb that is used in the brake light, rear turn signal and your rear back up lens. It's a very universal bulb. Fits mid 60s to 90s Mercedes.

These dash light bulbs are small in size and fit a number of dash light applications behind your instrument cluster and in your center dash console.

These small frosted light bulbs are 1.2 watts and fit applications where you want a dimmer light ie, heater control knob 240D and some other center dash lights.

These bulbs are 5 watts and they fit a number of applications for instance in your instrument cluster. Check to see how many you need.

These bulbs dont neccessary fit all models. This bulb is 1 5/8 inch long. Some applications require smaller bulbs, please measure your bulb before ordering this 6 pak.

These are correct Osram small diameter bulbs for your rear tail light. Use this bulb to prevent over heating of the lens. Comes in a 6 bulbs set.

This is a set of 6 front turn signal light bulbs. Fits early 70s to mid 90s Mercedes.

Heat shrink tubing is very handing to have if you are doing any wire connections or splicing. This tubing can go over the splice or solder joint and when heat is applied from a heat gun it will shrink right down tight to the joint and protect it from shorts and corrosion.

Good used black visor mirror clip for late 123 chassis with lighted mirrors on the visors. This one has good electrical contacts and is not broken. We also have in blue and palomino. Email us.

Fits all 5 cylinder turbo diesels from 1978 to 1985. Believe it or not these do go bad! If you live in the rust belt (ie salted roads) the lower alternator mounting bolt can actually seize in this bracket. When that happens the only way you will be able to remove your alternator is by cutting the bolt with a saws all and metal blade. Then you will need a replacement bracket like this.

Good used working right side mirror for late 84-85 123 sedans and wagons. Will not fit on coupes. Will fit on older models back to 1977 but you would have to power to it.  You would have to force adjust it by hand from the outside.

Fits 126 sedans 1981 to 1983 and 123 sedans and couples 1982 to 1985. This is a good working electric sunroof motor and housing. NO gears or clutch assemby parts are included. Unit also fits early 201 190E and 190D 1984 to 1986.

Fits chassis 116 123 126 and 201 Diesels with PENCIL glow plugs, from 1978 to 1989. This little strip fuse is located in the Glow Plug Relay and can sometimes be the cause of your glow plug problems. Even if it appears to be good, we recommend that you physically remove it and inspect it for cracks or breaks before you replace the Relay! Sold in a 2 pack.

Due to Kent's heavy product development and writting schedule he will no longer have the time to answer all the questions that have been pouring into our forum. Our goal has always been to be a resource to Mercedes owners who need help fixing their own cars. There is just not enough time to help everyone. We want to continue to try to help our current customers, so we are offering personalized tech help with your order of $75.00 or more. Some restrictions apply:

Application: Fits all 5 cylinder diesel engines 300SD from 1978 to 1985 and all 300D, 300CD and 300TD from 1980 to 1985 with pencil glow plugs. We have been so impressed with Monark Products that we have recently begun using their glow plugs. They are actually one of the last quality glow plugs still made in Germany. Even Bosch now makes their glow plugs in France, Turkey and other locations in Europe. Now don't get me wrong - Bosch is still a good product. But these Monark glow plugs are superb. They are built with the same materials and have the same specifications as the Duraterm pencil plugs. Even comes with 5 high quality locking nuts for the wires.

Application: Fits all 4 cylinder 240D diesel engines from 1980 to 1983 with pencil glow plugs. We have been so impressed with Monark Products that we have recently begun using their glow plugs.

FITS THE FOLLOWING: 115, and 123 chassis, 1975 to 1979 5 cylinder non-turbo diesel engines with series (looped style) glow plugs installed. WARNING: Be sure to check that your glow plugs have not been changed to the parallel (pencil)fast glow type.

Glow plugs do not last forever. I have found they generally need to be replaced about every 2 to 3 years for peak performance. If your diesel starts hard when cold, or starts but runs rough for 30 to 60 seconds before smoothing out, or the glow dash light flashes right after startup, then it may be time to replace the glow plugs. They should be replaced in sets unless you have the odd failure of just one fairly new plug.

FITS THE FOLLOWING: 110, 115, and 123 chassis, 1965 to 1979 4 cylinder diesel engines with series (looped style glow plugs installed. WARNING: Be sure to check that your glow plugs have not been changed to the parallel (pencil) fast glow type.

Cleaning out your glow plug holes from excess carbon (coke) can increase fuel economy and will extend the life of your glow plugs. This important regular maintenance procedure is commonly neglected and will lead to rough starts, smoke at startup, decreased fuel economy, and engine shake.
