Does anyone know where to find a chart of bulb interchange? Say you wanted a brighter bulb for a sidemarker or reverse light or whatever. Where can you find a chart of what physically interchanges? And how can you find what each one draws so you know how far you can go before putting in a thicker guage of wire. Thanks.

 

That should be all you need:

Cool. Thanks.
