Review on 🔵 Heater Climate Control Illumination, cciyu 6 Pack T4/T4.2 Neo Wedge LED Bulb A/C Lights (blue) by Brian Sage

I bought a T4 Neo Wedge LED of 6 to replace 2 bulbs in a Toyota climate control panel. I chose LEDs so I never have to replace them again due to the difficulty of replacing them. The built-in bulbs provided enough light for the controls, maybe a little less bright than the original bulbs, but still very functional. To make the replacement easier I did the following: 1) Using a small file (jewelry file or nail file/sandboard) I rounded off all the baseplates where the LEDs are mounted. Hold the LED so that it does not rotate while recording. It's good if the skin on your fingers loosens a little. 2) Test each flashlight with a battery (a 6v flashlight will probably work with any 4v flashlight and up) and note the positive side. 3) With the vehicle fairing open with the original bulbs removed, use a two-prong loopback tool (make your own) with a voltmeter to measure the +12V on the side of the bulb socket. 4) Glue the new bulb onto the end of a short screwdriver. 5) Align the positive side of the LED lamp with the +12V side of the lamp holding board and apply enough force to push and twist. Additional Notes: All six of my bulbs have been tested well. I measured the resistance of the bulb to be 900 ohms which means the current is around 10mA at a time, it shouldn't overheat. Added a photo of the LED bulb mounted on the left side of the panel and a rough loopback measuring tool I made from homemade AWG-14 wire and a bamboo skewer.
