Lightbulb D.I.Y. Door Safety and Foot Light on Santro

after not finding time for my earlier door/foot light, and couple of reminders from my fellow Bhpian I've
completed the door safety light on my santro.

Installation was damn simple logic :-
1). connect a Relay to prevent extra loads on existing wiring of cabin light, as this would come up sure shot when
any door is opened, no matter iginition is ON or OFF, car is running/stopped.

2). connected a Relay which gets on/off using small current from existing Cabin lamp.
3). connected a parallel wire from Hazard Light to relay so it provide current even when car is not running.

and its more of a utility than the bling bling factor.

Used L.E.D. Strips, using 6 Reds on Door, and 9 whites to lighten up the foot area, door opens and you know
that you are not stepping on to some sticky chewing gum,cow-d**

for 1 meter of strip you get 60 L.E.D.'s @Rs.250
you can cut it for each 3 L.E.D.
so using it for four doors you need 6L.E.D x 4 doors = 24 L.E.D. 30 incase you want boot door to also be covered.

Same is for white L.E.D. Strip. for each door use atleast 9, so you need 36 or 45 when including boot.

With all this much details, I am sure pictures would be able to speak much more than the words can.

Enjoy

Good stuff mate. Does look good and also sure, they help.
Not sure, if a relay was necessary as LEDs use pretty less current, may not be more than the relay actuator current itself.
Also please add a fuse to be more safe on wiring part.
Thanks for sharing.

Thanks all,
shyam, Relay is to prevent load and any shorts on original wiring.
i know L.E.D. don't put much load, but to avoid any possible wiring problems, I've used the Small Relay.

A fuse is already planned but not connected yet, as I'll be removing main power to connect other door tomorrow then the fuse goes in.

Err...it's gotta be the stupidest question around, but what's the utility of those lights ?

Ah...missed the 'stepping on cow-dung, chewing-gum etc..." part. Apologies. Cool DIY though.

yeah. relay and fuse will help, in case of any issues later.
i am planning to copy your efforts
I know it is not that easy one to complete with good finish as yours. needs lots of effort, patience etc.

^ But i am sure you have the same L.E.D. insect as of mine :-)

To make it stick longer you can use few drops of fevikwik on the self adhesive tape which comes along these strips, it would make it stay much much longer on the place.

Another point which i forgot to mention would be waterproofing, as door can get real wet when car is washed or in rains, so use a transparent tape to closely cover the L.E.D. Strip and it would be quite well waterproof, Cello-Tape would not let water get inside easily.

Nice DIY.

In the wiring going to the cabin light on the A pillar of your santro, what is the color of the "door open +ve" and "-ve ground"?

I assume black is -ve ground connected to the yellow cable you put ()2nd pic). What is your green cable connected to ?

UM

Hey, can you post some more pics of the same, but this time zoom out a little as it is a bit hard to make out clearly

Thanks

+ve which is coming from door switch is Blue Color.
-ve is brown, I don't remember now, but using the car chassis ground was not turning ON the relay so u used two wires.
3rd wire (which i didnt used is cabin light over-ride)
