Doing a semi-sealed beam headlight upgrade on my 'Maro, and while looking for new fog bulbs in a nice yellow color (which I never found, seems Eiko was the only company that made 50w yellow 885's and they quit production, the only ones I can find now are 893's which are 37w, and one site that has the 885's at a minimum order of 10, which is like, $90 plus S&H) I discovered that the 885's and a bunch of other foglights share the P29T base connector, along with the HB1 headlamp unit and the 9004 Headlamp unit. Both the HB1 and the 9004 are dual filiment lights, while the 885 is a single filament unit. I was wondering if anyone knew if the wiring for the fog lights would turn on the headlight bulbs, and if it did, would they be turned on to High or Low? If low, that'd be only five watts more of power (and since it's a Maro with the more open air fog lights than a T/A) shouldn't be a problem with extra heat. And if it's high, that'd be 15 more watts than stock, and I guess I'd just have to observe.

 

Don't know if this info will be helpful or not:
