Found best visibility, and its under 20 bones...

[K2 Kaiju]

So having gone the Spyder route the last few years, I just got sick of the poor visibility in rain. I picked up some chromed OEM type assemblys, and threw in some H9 bulbs instead of H11 (a trick we used on wifes old Traverse that made huge difference). Kicks ass in these too. I have included shots of h9 vs hid in spyder projector, h9 vs h11, 2 h9, the difference in bulbs (h9 has extra tab you got to shave off), and image of $5 h9 package. Forget silverstars - just put in H9s...

What a big difference.

I plan on rebuilding those Spyders with REFLECTORS for a change. Loved the plasma but just couldnt take the crappy projector output. I figure I could do a H9 reflector rebuild for pennies on the dollar...

I like those plain bulbs, last much longer than all the others (stock type).

Them 10 extra watts makes a nice difference. Thanks for sharing your findings.

 

[gooffeyguy]

Does the extra wattage cause any ill effects, like on the wiring or sockets?

Short answer: No. The high beams are 65 watt and they're fed by the same gauge wiring as the low beams and the plugs and sockets are all the same material.

Long answer: See inmypassatlife's reply. Now I have another small-but-useful project added to my list. lol

HIR's are nice, but H9's are a great all around upgrade to an H11

Lot's of good info in the link above.

Yeah, I'm likely to swap in H9s. My first project is to solve the voltage drop problem. I did this in my S10 days by replacing the stock wiring with 10 gauge- no relays or anything. Just replaced the factory wiring from the relay box to the plugs. The brightness of the low beams were equivalent to the high beams. A relay harness is much easier as the only wire gauge upgrade necessary is the short run from the relay to the bulb socket/connector.

Guess this is all a mute point for me. My headlights take H13/9008 bulbs that do both low/high beams. I'm not sure how those compare to H11 or H9 in fitment or performance

Doesn't really answer anything or explain why. Plus everything else in this thread is talking about upgrading H11 bulbs to H9. Nothing about H13

I ran a relay kit in a prior vehicle with excellent results.

Does a relay kit exist for our trucks?

I think his point was that, since there aren't many (affordable) options for the bi-filament bulbs, the next best option (really, it's what should be done in the first place) is to be sure you're getting 12-14 volts to the bulbs, stock or "special", in the first place.

Probably. My experience with pre-fabbed relay kits is that they use small gauge wire with thick insulation, making it appear as a larger gauge. They also use crap quality relays. Personally, I'd get some quality relays (and weatherproof sockets if so desired), wire and connectors/terminals off Amazon or eBay and make my own. You'll be able to route the wiring where you want and won't have a bunch of extra to bunch up and zip-tie somewhere.

As always, I'd research a little first. Someone just may sell a pre-made harness that even OCD-crippled people such as you or I would approve of. They may have it marketed as harness for a Silverado/Sierra, so include that in your search criteria. I'm gonna dig a little while it's fresh on my mind.

I made my own with some 8 Gauge wire and some halfway decent pre-wired connectors and sealed water proof relays, tried some regular off the shelf relays at first and they crapped out in the summer after only a couple car washes, then I had to mount my ballasts with the harness facing down also so no water would sit and creep in them, since then no problems
