Can someone tell me what are this "pipes" or tubes attached to the 2017 ST LED turn signals? They look like glass pipes.
I can see the first part. Makes sense.Juan Valderrama said:It is a resistor. It's glass or ceramic, it dissipates better the heat and it's needed to make the turn signals work ok.
In short, yes. For example, if you decide to keep the OEM flasher relay in on the 2012's, then you need to fiddle with inline resistors to delay the rate at which the 12v pulse hits the LEDs. The inline resistors simply act as the amount of resistance the incandescent bulb would have so it achieves the same flash rateMaxified said:Do LED's require more resistance in the circuit? Sometimes an LED replacement kits come with a component to help them work with the OEM circuitry so you do not get the rapid blinking.
I didn't see anyone answer your question, so I will. You are correct that the LED does not make much heat. It's the resister that makes the heat. Even with electricity, resistance is like choking down the flow, and just like the resistance of your tires to the pavement, the higher the value, the greater heat generated as waste result. Everything has an opposite and equal reaction. The resister is mimicking the electrical demand of a element type bulb in order to allow the flasher to respond with the correct pulse. A common farkle when adding LED signals is to replace the flasher with one designed for LEDs too. Here is one version: CLICK ME Doing that allows you to skip the resister use, in most cases.Karson said:I can see the first part. Makes sense.
I'm curious about the heat part. LED's are one of, if the not the most cool and tough type of lighting out there.
