Description

Factory upgrade the dome light of your Toyota IQ.

I designed a small adapter plate in order to mount an angel eye ring to the factory dome light of our beloved Toyota IQ!

After printing ensure that no support material is on the surface because the tolerances are very tight. Use a file to smooth the side that had support interface on it. I have successfully installed this mod on many IQ and never had any problems. I strongly recommend the printing material to be ABS in order to handle the heat temperature range of a cars roof. I personally I haven't tried PETG, but I have include a profile for those who will dare.

Tested on my IQ, over 3+ years since installation, no sagging or any other defect.

 

Installation steps:

  • File away the support material and ensure a smooth and clear surface with no edges that can be caught on the roofliner of the car.
  • Disassemble the dome light, by first remove the PCB, unclip the two half's by the 4 clips and fit the adapter on the dome light.
  • Align the PCB to the outer transparent housing by doing some dry test with my adapter. Then when everything aligns use a flexible adhesive glue, I used T-7000 because that's what I had laying around. The transparent legs that will protrude you can either snip them up with flush cutter or I recommend to use a soldering iron to make a physical connection between the printed material and the angel eye outer housing, that way you will never have them separate even in the very hot summer days.
  • Assemble everything and make your electrical connections as showed in the pictures below, positive and negative cables.
  • During the fitment to the car you will notice that the ‘new dome light’ will not clip in place and will not hold it's place because of the adapter. What is happening is that it needs to be moved slightly to the side opposite of the metal clip with a decent force (driver side for the LHD cars). Just to simply push the unit to the left and down towards the ground and only then try to clip it. After a bit of maneuvering and a light nudge the clip should click in place and the unit will be secured on the car, that is the only hard part of this job but it works on all the cars I have attempted it.
  • Final step, i used a black TESA 51026 cloth tape in the outer side of the angel eye in order to reduce the direct contact of the light source with the eyes, i found myself a little annoyed by it and decided it wouldn't hurt nor give any negative effect in the overall coverage. You can see this tape in the cover photo if you zoom in it.

My approach is for the angel eye to work as seamless as the factory unit. So the angel eye is tapped on the power line of the led and keeps all the functionality of the body control module, lock/unlock lit, fade, always on, always off, etc.

READ THIS!

The angel eye is super bright if you just take the power from the the factory dome light, the brightness will shock you. They may be a dangerous event where if someone turns it on during nigh driving, it will blind you no joke. Consider installing a resistor with a value of 20 ohm in the positive cable between the led PCB and the black driver housing. This is in order to protect the BCM from working to hard by limiting the current and stepping down the brightness of the angel eye. That's how i have implemented it in every car that i have install this. You can experiment of course with a lower or higher resistor value in order to suit your needs for brightness.

 

20Ω Resistor in the positive cable

 

For reference this the cabin with no resistor installed.

 

 

That's all, I hope you find my tutorial useful, if you did i would appreciate a boost!
