I stayed at a Holiday Inn Express... The turn signal bulbs are 1156, the corner and horn bulbs are 194.

The 1156 = 2.10 amps and generally are around 27 watts

The 194 = 0.27 amps and are generally around 5 watts

I tried doing without the inline resistor and short of buying several different E-Flashers for trial and error (Some work, Some don't), I gave in and did the inline resistor anyway. If you do come up with a different solution, please share.
