I apologize if this has already been covered. I’ve attempted to upgrade my stock halogens to LED. High beams work fine and drl also. Fog lights no problem. Low beams work until I start the truck then cut out pretty quick. The lights I bought came with CANBUS. Now the manufacturer suggests I buy resistors also. Everything I’ve read says these resistors run very hot. How are guys mounting these when the headlight housing is an all plastic sealed unit? The resistor they recommend is a CAS-TWO which looks to be a resistor inside a plastic case. Do they run cool enough to put inside the housing? My truck is a 2019 Ram classic . Side note: I used the exact same lights to upgrade my last truck a 2017 ram express with no problems. These 2 trucks are near identical aside from 8 speed,hood and tailgate so it’s left me scratching my head.
