yellow high beam?

HW bulbs typically have shorter life due to heat during working life when they are at full bore; if they are seeing a modulated voltage they act like normal bulbs. they will be fine. Also, the wires in hondas, esp the later models, work fine with well constructed high wattage bulbs. if it was a vw, then id' think twice about it. hella bulbs don't pose any unnecessary draw or extraordinary needs like some of the 'high wattage' asian bulbs out there. i use hella premium HP bulbs in my 07 si, HW for the high beams and dot wattage for the lows and have no problems

silly noob
you don't know anything about current, electricity, voltage and how DRL's work. They're not the same in every car.

wtf are you talking about? explain yourself.

OP asked about yellow high beams in his 07 si. i reco'd high wattage yellowstars. someone said no dice on high wattage in the high beams on the si due to DRL's. i have high wattage bulbs in the high beams slash DRL's in my 07 si. they've worked perfectly

/end.

Let me explain you how the DRL's work.
There are three type of DRL modules for cars.
dual filament using the low beam filament as DRL as almost normal wattage.
You have the low-beam DRL's that have the standard 51Watts and run at 6Volts.
Then, you have the High-beams DRLs that run the standard 65W and run at 10Volts.
Adding a higher wattage bulb that is 110Watts, you will still exceed the wattage OEM wiring is supposed to handle. Because our cars use DRLs, running a high wattage bulb will pretty much:
a) decrease the bulb life thus buying a set every 5 months or less.
b) the wattage sustained will slowly melt away the harness
c) This is how it will look under the dash:


you think the higher wattage doesn't do shit to your harness but using 10V, the bulb already exceeds the wattage allowed by the stock harness. Everytime your DRL will be activated, there will be stress on your stock harness. Do that everyday since everytime you release your e-brake, your DRL's will be activated , you're allowing at least 90Watts to be turned on, your harness will go buh bye in no time. You may not see it physically but let time pass by...


VW have a different DRL system unit that follows the dual filament pattern.

Also, our 9005 harness uses 18ga wires. That alone should give you a warning.

i never talked about vw drl; i mentioned vw solely regarding issues with wiring, if running high wattage bulbs in any beam on a vw (or any german car for that matter), i'd be wary due to the lame tiny wires from the housing plug to the bulb plug. look back to the sequence in my previous response and you will see that-

the high wattage 9005 yellow stars were in reality 80w but they no longer make yellowstars so it's a moot point. they have 65w optilux xy now...

anyway- i run the high wattage Hella hp's as stated and do not have any hot connectors, melting wires, burned bulbs, etc and have gone on long trips in my si. so that's why i'm debating. if you are supplying 10v to a bulb rated at 13.5v and let's say 100w at said 13.5, why would it cause an issue? it's now effectively a pretty low wattage bulb because it's not consuming 13.5v because it CAN'T, it's consuming 10v which would lower it's effective wattage. is the 07 si headlamp wiring at the housing any more frail than what they've use in honda's past? i've always run 100+W bulbs in all of my hondas in atleast one of the beams, if not both like my 6th gen (h4). i've not looked, but are you sure that the highbeams on the si are not using a relay setup seperate from the drl supply?

bulbs run at 11.5-12V. The 13.5V is a spike caused by the bulb itself that as a result will put stress on the stock harness.
Again, our stock harness is using 18ga. They're not using 12ga or 14ga...
Here you go:

Yea, if you rewire your harness with a larger line it won't be as bad, but the way it is, it's not worth it.

Personally, i'd just use normal wattage bulbs no matter what color I wanted the light to be just for safety and reliability's sake.
