As title,

Does anyone know the difference between the two types?

The car needs W3W side lights according to the manual - I have lots of W5W bulbs sitting around. Are they compatible? Google doesnt really help and image search suggests they look the same.

Insights welcome!

As far as I can tell they are both physically the same size.

One is a 3 watt W3W. The other is a 5 watt W5W

W3W is possibly a common American size. What kind of car is it for?

Beaten to it

Gotcha cheers.

'Wedge 5 watt' makes sense I guess smile

Its for a Jeep, so the American angle is correct.

One more stupid question.... consequence of using a 5w, when it should be a 3w?

It will draw more current.
Current drawn = power divided by voltage
On a 12V system the 3W draws 1/4 amp. The 5W draws 5/12 amp
