what is shady about him? the fact that he may not tell you what you want to hear?
Dan has already had TONS to do with the available products as well as the laws governing their use.
He WILL tell you exactly what you don't want to hear if what you want to hear is that a crap product that your friends recommend is a good, safe and legal for use product.
Just keep in mind as some have mentioned already, that the MAIN reason headlights suck in our cars is the wiring (the available voltage and amps) to the headlight bulbs.
Using relays puts a much more capable power supply closer to the bulb that needs it instead of the headlights getting their power supply from a small 12 or 14 ga wire that runs through all your under hood, bulkhead connector, dash and switch wiring and then back out to the headlights to light them.
Having done it myself, I can confirm that the lights (any lights) are WAY better than with the factory wiring (plus it takes all that heat generating power sucking load off of your switches) which is a good thing.
Knowing what I know now I would never try to solve that problem with bulb changes only, as it's a complete waste of time and money without having a good supply of power.
1. Relays
2. Even just decent bulbs.
3. You will probably never need a 3. :D
