Re: Roof Driving Lights


hmm yeh ill look into it see what i can dig up...
interesting to note that when i was installing them, i had crossed a wire and the result was one light working and double the normal intensity and the other one of the pair wassnt working at all, imagine having all 4 just like that single one emoticon
that would be ultimate bunny hunting material emoticon

Re: Roof Driving Lights


Thats a good looking mod mate emoticon
With the current wiring and increased amperage relay, you could either parallel the existing wiring (just run 2 of the same size conductors to each point to decrease the resistance) or swap it out with a larger power "feed" to your lights, as well as the earth points.
Either way, that looks darn good

Re: Roof Driving Lights


Hi Cam,

The 4 x 110W lights equal about 32 Amps current @ 13.8V so with the two relays each will need to be atleast 20 Amps capacity if you are powering 2 lights from a single contact or 10 Amps capacity if each relay is a double pole type and powering a single lamp from each contact of each relay.

Again, with a total of 32 Amps you should either use heavy-duty wiring for the power feed to the relay contacts or use a separate power feed wire to each relay. Otherwise the extra voltage drop due to the current capacity of the smaller wiring will have the lamps dimmer than you would expect.

yes. i bought a wiring kit that catered for 2 spotties, bought an extra relay that doubled the amp rating of the existing kit under advice from a relative (auto electrician) - i cant remember the rating before you ask... and used that to power all 4.



So did you just put in another relay and use the existing wiring for the one set of 2 spotties, or did you run a second lot of wires from the second relay? By only doing the first method, you're not achieving anything, and the cabling going to the spotties could be overloaded. The next quote indicates you've done it this way.

on that topic, i can imagine because im powering all 4 with wiring that caters for only 2, i can potentially get more bightness out of them with alternative wiring cant i?



Thicker wiring will reduce the voltage drop and thus make the lights brighter, however the difference in brightness may not be very noticeable.

Ideally you should've bought two wiring kits, or alternatively duplicated one kit yourself, or used a relay and fuse which was double the rating of the original kit, and increased the size of the cable going to the lights.

I just read the last couple of posts and I think between the three of us, we've covered all bases emoticon

And you'd get a rather warm back as well!

Re: Roof Driving Lights


beautiful...
time for some fix-it jobs tomorro night.

should be easy now that all the wiring is already running through the car, just need another kit w/ some extra wires.

shall post changes + finished product.

thanks for the help!

EDIT: bought an extra wiring kit and some more length of wire...
what a difference!
i though the lights would just be double the brightness but they seem like more than twice the brightness for some odd reason
when parked in my garage they make a more intense light patch on the wall than the headlights themselves, even on highbeam.
will post a pic later.
thanks for all your help.
PROJECT 'ROOF MOUNTS': done.

p.s. Rich, lucky there's enough room BEHIND the lights standing up out of the sun roof, or i/the shooter will be the one thats getting owned, not the bunnies...

Re: Roof Driving Lights

=============================

I recently added roof lights to my racks.

they compliment my driving lights on the nudge bar as well.

I opted for, four yellow tinted fog lights as my town of residence is carpeted in pea soup fog, 200 mornings each year.

I also used gutter mount racks as they were free.

I did have to make adaptor plates, and I will post pics sometime tomorrow if I get a chance.

took a few pics tonight of the setup in action:

Don't know how effective the fog lights will be on the roof.
Fog lights are meant to be mounted low so they project under the fog layer rather than through it.

=====================

I understand the concept, and have considered that.

However upon testing last night, they did seem work well in tandem with the factory fogs.
Though I did have to do considerable adjusting.

As the fog here is usually fairly low lying, I find that the roof racks sit just above it.
in full fog, the effect seems to be much the same as shining a torch at the roof.

I get a soft reflection from the "ceiling" created by the light beam that illuminates objects for some distance.

I have pics of the lighting pattern, but will post only if needed.

I am able to make out white lines from a far greater distance, and having four lights allows me to adjust the spread to better view the roadside.


This is aimed mostly at my upcoming trip over Mt Hotham, where there are orange marker poles to mark the side of the road.

My main objective is to keep sight of those should the conditions go bad like they did last time.

Low to the ground lights did not seem to work on my last trip, in fact they appeared to make matters worse.

However, I can only speak of my own experience but what I can say, is that in theory, is not always as in practice.

I have some further pictures for those who are interested in the rack mod and lighting configuration:

Apologies for the image rotation, I am on my Linux machine and have yet to master the built in image editor, I will update and re-upload the images when I am next on a windows machine.

Re: Roof Driving Lights


Dave,

There are things which you need to consider with this mod and I had this type of set-up on my own exy before fitting the hyper roof rails with lights.

1. It is illegal and can only be used off-road. If a cop spots you with these driving lights on, you are in trouble, even in fog conditions.
2. You will have to remove the rack with the lights at rego renewal time because it won't pass rego.
3. To achieve point #2, the easiest way is to have quick release harnesses on each side of the roof rack, so you can remove the rack along with the lights with ease and without fiddling too much with the wiring.

Since the theory is that you can't use these roof lights only in off-road conditions and they should only come-on with the hi beams, having fog lights on the roof won't achieve much of lighting and that is why you see big 4WDs having large spotties at the top, to get as much light as possible off-road at night time.
