Making turn signals in mirrors by ourselves
Hi All! Been wanting to … finally did it. What do we need? double sided adhesive tape, LM 7812 krenks (stabilizing)… and LED modules ordered from Celestial. The entire process of introducing is shown on the other cars look their manuals for disassembly mirrors.
Carefully pick up so screwdriver and remove the corner.
With a 10 head screwdriver unscrew the 3 screws…and remove the mirror.
Also, using a small screwdriver, unscrew two catches and remove the mirror element
On the photo clicks to be clicked on the arrows … The mirror itself is simply inserted into a plastic frame, to remove it was easy, but to clean the adhesive from the mirror … Here I sweated over each for 30 minutes, and then cleaned not all, but only those places where there will be modules … cleaned with plain water.
LED module glued to the frame with double-sided adhesive tape
Slide the mirror in place…well, just like it was there…shown with an arrow
The mirror with module is removed to the side and disassembled mirror housing and mechanism to pull through the power wire. Unscrewing three screws… they were a little bit hard… I hardly unscrewed them
The three screws that hold the mechanism to the case…and remove the case…it does not come out at once, but after twisting it back and forth, it does.
Then unscrew the three screws that fasten the mechanism cover…also indicated by arrows
Now pulling the wire through next to the main harness.
That’s it! The wire is pulled through…assemble in the reverse order.
Connect the wire pulled through to the module wire.
Connect through the breaker bar … pull the wire to the turn signals, I powered the side (green wire + … white -)
Scheme of connection of krank
Pyssy: bought adjustable voltage regulators LM2596, put them instead of krenok))
How to make LED turn signals in the rearview mirrors
If you want you can make the required LED assembly by yourself by placing the elements on a piece of appropriately shaped piece of textolite. Do not forget about the current-limiting resistors, without them the LEDs will quickly fail. It is not advisable to use diodes with more power than 1-2 W. They are warm during operation and despite the fact that we will include them for a short time, they require installation on heat sink plates. A circuit variant for LEDs with a voltage drop of 2-2.1 V is shown below.
Because the size of the electronic part of the device is quite critical, it is best to make the circuit in any tracer program and mount it on a printed circuit board. We will use a ready made LED assembly from Aliexpress. This will cut the time to assemble the repeaters many times over. The price for a pair of these arrows is about 100 rubles – http://ali.pub/4hsw0i.
Algorithm of assembling the device
Using solvent (gasoline or acetone) remove the protective layer. We apply the solvent in small portions on a cotton swab to get a clean area with smooth edges.
Drill a small hole in the corner of the mirror housing so that you can lead out through it the wire from the turn signal repeater.
The wire of the LED assembly will run along the rearview mirror mounting bar, fixing the entire length with heat shrink tubing of the appropriate diameter. It is better to choose a monochrome tube with no extraneous inscriptions. This way the construction will look more aesthetically pleasing.
Connect the LEDs in parallel to the turn signal, observing the polarity. It is most convenient to do this on the connector chip.
Done! Now in the dark, when the turn signals on the rearview mirror will be flashing colored arrow. Looks very impressive.
