I'm going to put Depo Euro lights on my car. What is the best bulb to work with those on a W124?

The seller says "The manufacturer recommends utilizing halogen/incandescent bulbs in which are the following size: H4 (High/Low), H3 (Fog), W5W (Euro City Light)".

When I look online for H4 bulbs there must be 50 different types. 9003, 9004, 12v, 24v, 62248, and lots of other types. I'm assuming the same goes for the H3 bulbs.

Thanks,
