What headlights do our Benzes have? H4 or H7? Or both?

[Rollingstone]

Hi folks,

I'm thinking of removing my old OEM headlamps tomorrow, and replacing them with Silverstars I mentioned in one of my posts earlier this month. Thing is, the Osram guidebook at my supermarket doesn't list our W126s, so I don't know whether I should buy H4 Silverstars, or H7 Silverstars. Or are there 2 headlamps on each side? (i.e. H4 + H7?)

I know some of you'll now be saying, "remove the lamp covers and check for yourself". [:D] Ordinarily, yes, I'd do that, but it's -6 c outside now, with a freeze-your-butt-off windfactor, and so I'm just going to have to buy them, and get to my friends (far from that store) to install them in the warmth of his heated garage [;)] tomorrow, but of course I need to know what to buy before I get to his garage.

So, please advise, asap, on what number I should buy.

Many thanks,
RS [:p]
