My w124 has a sealed beam and it has the headlight and the fog completely sealed, there is access from the back. I dropped by advanced auto parts and cross referenced a sylvania replacement bulb for the fogs. It looks like the factory ones are 55w but the replacements are H3 100w.
My question is will this wattage increase burn out my wiring or should I be OK? I bought two bulbs figuring I will swap out both but before I make a mess of the wiring I figure I would ask for input...any feedback for me?
Should I just go to Mercedes and look for the OEM fog bulb?
thank you
