2017 Mitsubishi RVR Bulb Advice

[jzchen]

I can't imagine new wiring would cause much voltage drop. Why not measure the thickness (gauge) of the wiring going to the bulb, and report? (Wiring thickness is what determines how much current can be carried, voltage being equal). The wiring on my iQ was surprisingly thick, in my humble opinion. Even though another member on the iQ forum I'm on is still scared to try H9s, I went ahead and installed a set.

Because wiring thickness doesn't tell you the quality of the conductor, nor the quality of the terminations.

Instrumented testing is the only sure way to know.

Measure the voltage drop.

(Yes, it's probably safe to make certain assumptions, but really, the testing is so easy to do (even the correct way) that it doesn't make sense not to.)
