Running Light Question - Air Cooled T100

I am planning to replace the bulb in my 2013 T100with an H4 LED. There is a second bulb at the bottom of the headlight assembly, i presume that is called the daytime running light? Anyone know the bulb specification so I can order a replacement before I take apart the light assembly?

 

They are usually a W5. If you’re gong for a led headlight get an led sidelight bulb as well otherwise it will look yellow compared to the headlight. There are loads on eBay, have them on my St 1050. Sometimes you can only fit them one way due to polarity, if it doesn’t work turn it around.

 

that's called a park light in aus as the headlight is on all the time mine had been removed when I bought the bike, as it does nothing I haven't put it back
