Well, this is not going to be as easy as simply swapping out bulbs. The existing LEDs are in a custom housing and have resistors in the electrical path. Here are some images of the unit I pulled out from the passenger side. Any EEs out there with some suggestions?
It's amazing you even cracked that thing. I couldn't figure it out. Is the color temp still amber? Are you looking to change to white? If so, I may have an easier solution for you.
There's a thread in the Gen3 main forum where a guy found a Lexus part, same part, but with a white LED. I think it was from a ES350. Footwell lighting??? | Page 2 | PriusChat I see you posted in that thread.. so are you trying to do something different than just white LEDs?
I want blue to match the illuminated door sills and courtesy LEDs I have in place now. 2012 Mods | PriusChat I just put in an order for a variety of LED bulbs / fixtures to see if I can find something that works. My concern without seeing the output yet is how bright these will be --- I am looking for something perhaps only a bit brighter than the original foot well intensity. At least I now know where to tap power to get the rear seats illuminated. new iPad ?
On the sixth and last photo, the electronic component in the center next to the LED is a diode. A diode is used to keep the electricity going in one direction - this means the LED is a uni-directional LED and is suppose to get its electricity in one direction ( if that is not obvious by now). The electronic component to the left of the diode is a resistor which lower the current level of the electricity before it passes through the LED. The bands on the resistor white-brown-brown-gold describe its rating <band1><band2> x 10 ^ <band3> ohms with an error accuracy of <band4>[1] The color scheme for the first three bands is describe by an old engineers mneumonic device. bad = black = 0 boys = brown = 1 rape = red = 2 our = orange =3 young = yellow =4 girls = green = 5 but = blue =6 violet = violet/purple = 7 gives = grey =8 willingly = white = 9 the last band, band4 is described the tolerance/error of the resistance with the most common designations as follows: <no band> =20% error tolerance silver = 10% error tolerance gold =5% error tolerance for example the resistor band in your photo is white brown brown gold 91 x 10^1 ohms @5% error = 910 ohms @5% tolerance. It's likely that the wiring/current goes on a simple serial path the positive prong/lead - resistor - diode - LED - ground/negative prong/lead. Manufacturing wise I would guess that the ground lead of the diode and a lead from the negative prong are threaded into the metal casing up through the LED housing and through the LED light view port, then the leads are soldered/connected to the LED, then finally the LED is pushed down into light view port. To take the LED - you would poke a screwdriver/thin blade like tool and crowbar/lever/pop the LED out from its viewport opening. hope this helps Walter [1] Electronic color code - Wikipedia, the free encyclopedia
Did anyone crack this nut...? I too would like to get some blue LED's and use the factory mount setup. Thanks, Mark
I order these last night... I'll tell you how it goes. SHARE STYLE | Rakuten Global Market: for a Toyota (Toyota) car general-purpose inner lamp LED illuminations step light (foot lamp)! White / white / red / red / blue / blue / pink
