I heat the rods up with a heat gun till they are almost soft and then drill the holes with a fixed press... I used hightemp glue last time and it did a pretty good job of diffusing the light. I had 40 degree wide lens color LEDs last time & my new white ones are only 20 degree but they are twice as bright so I'm hoping that will make up for the difference in viewing angle.

unfortunately I'm working on a rather small budget (100$) so there wont be any strobe effects controller as my last set had. Though I may try to build one on my own but that would be a large undertaking. I'm still working on the voltage regulator. I thought about using the same one as my foglights but I'm open to more efficient.

Do you have any expertise to lend me on building the strobe controller // voltage regulator?
