A major enchancment might be made to the efficiency of Mercedes 126 headlights by changing the DOT-approved items with real European headlights. There may be additionally a significant aesthetic profit.

Significantly within the case of the early (first-generation) 126 vehicles previous to 1986, the DOT-approved headlights for the U.S. market had been horribly inefficient in comparison with the Bosch lights put in in Europe. The pun is barely excusable, however the distinction in mild output is sort of night time and day. One can solely assume that this lamentable state of affairs was the results of federal rules drafted on the behest of sure congressional chairmen defending the business pursuits of companies inside their districts. The foundations elevated demand for conventional, sealed-beam headlight items on the expense of highway security.

Real H-4 “Euro” lights are nonetheless out there new from Bosch however are very costly. Thankfully, good used items might be discovered each domestically and from European sellers. And there are after-market copies from corporations like Depo which look nearly nearly as good (however aren’t as nicely made). The glass lenses might be purchased individually within the occasion of injury, however inside elements are now not offered individually.

Along with a superior reflector and lens design, Euro lights supply the Mercedes proprietor the pliability of straightforward bulb modifications with out changing your complete unit. And the efficiency of the lights might be enhanced even additional with high-output or over-wattage bulbs. Having mentioned that, one ought to be leery of imposing an extreme load on the wires to the lights. Whereas Mercedes wiring is best than most, there comes some extent the place extreme warmth might harm the wiring and voltage drops would impede efficiency. These issues might be obviated by using relays. However for many drivers, the output from the usual European bulb might be greater than satisfactory.

European headlights additionally supply a metropolis mild — a small, 4-watt bulb which might simply be wired as much as the prevailing circuit for side-markers, offering further ahead identification. And for gadget lovers, there’s a vacuum-driven height-adjustment function which can be utilized to regulate the lights from inside the automobile when carrying heavy cargo. Some understanding of the automobile’s vacuum circuits is required for this modification, however it isn’t tough.
