Why do motorbikes....

[oz_borne]

...have only one light that comes on when they are in 'sidelight' mode. Do they not have small sidelight bulbs like cars???? i just wondered cos if you saw a car like it, it looks stupid....and in my opinion it does on the car too.

Any ideas?

:A:

Always wondered this too... Looks like they have a bulb out.

Bikes use their lights to make you aware they are there... most bikers do this anyway. As you often notice the light more in the day than if it wasnt on.

Makes sense really as many people fail to appreciate bikers on the road.

simo is correct, alot of manufacture now make the dip beam come on with ignition for safty. two of my brother and dad ride and they have all been hit by bumholes in cars that dont pay full attension. trust me bikes need more than a light to be safe lol.

My front bulbs only light up one at a time, and yes, it looks like one has blown - one dipped one full beam...only one will go on. I have a side light too, and its a little bulb - just like car sidelights!!!!
