What physical size of bulbs/bulb housing did you use? I don't really want to drill a hole to find out the setup I chose is to large for the spacing on the inside of the headlight. Any recommendations? Thanks in advance!

 

The bulbs I used are led 194 in amber color,as far as the housing I don't remember the part #,but they are for a Ford side marker light.I purchased mine @ Autozone for about $20.00 for all.
