I wonder why you are using "27A" cable? If you are running 55W bulbs then max current is a little over 18A in the real world it is likely to me nearer 16A.

Why do you say that? Real world figure tend to be fractionally higher due to the fact that alternators run at about 14volt and thus nominal 55w bulbs are actually a bit more powerful than that and draw more current. You can't calculate it cos the resistance of the bulb changes as it gets hotter due to higher current being passed, but there is an effect that way. If you're seeing l;ess its probably due to voltage drop cos you're using cable barely up to the job, always over spec by a decent percentage, and personally always build for the maximum that might be used so build it for 100w bulbs even if planning to us 55w, you may want 100watters in the future and re doing from scratch would be a pain and expensive.

Tell you what, mount the lamps to your car then bring it over one day with a fistfull of beer tokens and I'll do it for you :wink:
