i never heard of someone putting the resistors inside the housing.I converted to LEDs both inside and outside, and I did not install resistors to eliminate the hyperflash. IMO, the LED with hyperflash is actually more noticeable to other nearby drivers, thus making them more aware of my directional intentions. Also, I did not want to put resistors that can heat up within the plastic light housing (probably a very small risk of melting/burning anything in any event).
I understand that hyperflash is illegal in some states, so any decision regarding the use or no use of resistors would need to take that into account.
