I'm heading across to the west again and have decided to upgrade the headlights in the VY. Although the lights are fairly good, I thought I might go for either 90/100 watt in the main part of the headlight or 100 watt in the spot light part.
Is there any problem with this upgrade due to the plastic lenses or wiring?

Thanks Terry but when you say low UV, is that something to do with the k rating? I had 100/130's in my J but it had glass lenses.

if you want good clear bright lighting go for a hid 35watt kit way brighter than a 90/100 watt halogen less heat better lighting but illegal in most states but so are 90/100 watt halogen

Thanks for all the suggestions but I saw my model with driving lights on a light bar and liked the look of them. Went and bought a set of 100 watters and a bar. I''ll be putting them on tomorrow.

What state are you in? I'm in Vic and there's nothing in the vehicle regulations here that say higher wattage lights are illegal. They just have to be the same output left and right.

All done that way John but thanks for the info anyway. I have run a relay and fused that as well. They are fitted as required by the regulations into the high beam as in they only work when on high beam as well as an inline switch to stop them working if I want. I probably don't need them as last time I went, the standard ones were ok but I prefer to see a bit more, especially if I start early or run after dark like I did last time. I had no problems with wildlife and did do a bit of dusk and dawn driving as well. For your info if you are interested see the ADR copy and paste.
ADR13 specifies
7.3. DRIVING LAMPS

7.3.1. Presence: Optional on motor vehicles. Prohibited on trailers.

7.3.2. Number:

7.3.2.1. Two or four.

7.3.2.2. To be used in conjunction with headlamps.

7.3.3. Arrangement

No individual specifications

7.3.4. Position

7.3.4.1. In width no individual specifications.

7.3.4.2. In height: no individual specifications.

7.3.4.3. In length: at the front of the vehicle and fitted in such a way that the light emitted does not cause discomfort to the driver either directly or indirectly through the rear-view mirrors and/or other reflecting surfaces of the vehicle.

7.3.5. Geometric visibility

No individual specifications.

7.3.6. Orientation

Towards the front.

7.3.7. Electrical connections

The driving lamps must be able to be lighted only when the main-beam headlamps switch is in the �lamps on� position.

7.3.8. Tell tale: No requirement.

7.3.9. Others

The aggregate maximum intensity of the main-beam headlamps as specified in paragraph 6.1.9.1 of Appendix A can be exceeded with the fitment and illumination of driving lamps. Driving lamps do not have to comply with ADR 46/�.

And Appendix A
6.1.9.1. The aggregate maximum intensity of the main-beam headlamps which can be switched on simultaneously shall not exceed 225,000cd, which corresponds to a reference value of 75.
6.1.9.2. This maximum intensity shall be obtained by adding together the individual reference marks which are indicated on the several headlamps. The reference mark "10" shall be given to each of the headlamps marked "R" or "CR".

As my headlights are marked with an R and are standard globes, each of the high beam (4) equals 40, well under the 75 maximum. As you can see from 7.3.9, driving lights do not have to comply with ADR 46 which is the lighting requirements. However, both of them are also marked with an R so even if I have to add another (2) totaling another 20, I am still under the 75.

Even the police over here fit driving lights to their cars and have the same arrangement to what I now have. I have been a member of the Victoria Police Highway Patrol for over 29 years and am well aware that they comply with the regulations so I don't think there should be any problems.

Looking forward to the trip in 2 weeks today but again, I'm only going as far as Kalgoorlie.

thanks again....Andrew

I never thought of that. Might give it a try.
