I run over 500 watts of lights on my truck Go the 80 amp alt!!
Im planning one day to up my main bulbs to 130/90s. I'll be running a wiring kit with relays as I dont belive in those 'uprated' bulbs either. By just changing the colour of the light emitted a lot of lights 'appear' to be brighter where as they often arent. Ive had very good results with putting in relays for less voltage drop, so Im old school and will stick with it, also thats what Id advise also.
Ive still got a loom designed for toyotas that has 2 earths, a positive lead, 2 bulb sockets and a plug to attach to original wiring harness so its REAL easy to fit. Reason for a new loom is because toyota do a funny thing with there wiring that uses the low beam circuit to power the high beam warning light on dash, which makes 'just fitting relays' a little harder.
Cheap and easy way out, go the 'uprated' bulbs.
My recomendations for GOOD lighting, higher wattage bulbs with GOOD wiring and relays.
