So making the connections and wiring very low resistance - eg thicj cables, and switched with a quality relay, does this mean you will drastically shorten bulb life (if you could get near to 14v across bulb?

[Marks DTM Calib]

Possibly.....the bulbs as stated appear to be rated at 13.2V....so this would be about the optimum I would say.

Not an issue with HID's as they use a stabilised supply thanks to the use of a DC-DC converter

i got some ov them, 100 watters   is that common practice?

No & it's very naughty!

Maybe so.  But before HID etc police sars used to fit 130 watt bulbs, so I dont understand, if it's ok for plod, then why not for all road users.


Lets face it, rules is rules.

100w or 130W is approx twice the current. Will the relay, wiring & fuse stand that?

Yup, was only thinking about halogens, and not thinking about any car in particular (both mine have reasonable HIDs, and the Rover has pretty good lights), just thinking around the theories


Saying that, might be worth looking into improving that main beam on the Omegas, esp if I put chavvy bulbs in to match the HIDs?

Not tried on Omega, but never had issues with other cars...

MDTM - as the wiring/switches/contacts/connectors etc age, is it likely the resistance will increase?  Is this another reason why older Omegas seem to have poor lighting?

Have u fitted HID's yet?  
Omega projectors are useless with standard filament bulbs  
Makes me wonder why they fit projectors really......
Ive got standard filament bulbs, non projectors on my Viano and they are great....bright....do the job fine.....so why buggar about with projector lenses??  :-/ :-/

Interesting reading btw

I agree with TB, have tried all sorts of bulbs over the years.  100/55. 100/80 and even 130/100 never had any issues.

Would be interesting to know the cable size and therefore work out what the wiring can/could cope with.

[Marks DTM Calib]

Cable size is easy....

its 1.5mm stranded....this will take around 5 amps.....which gives just over 60 watts.

Interesting..

my ex car was weak on the lights also..after an upgrade to 100W

it became really good..

      And miggy with original lights (even with new head lights-I changed to new) was a shame for that good car.. So definitely HID..

[Martin_1962]

On a previous car I had 460w on full beam with the driving lights as well

160w total dip

And I ran relays from the battery

yep..for upgrades relays necessary..Was Bosch if I remember correct..and never had problem..
