Lasfit LED turn signals + Diode Dynamics XPR Reverse Lights.

[CivicSportSGP]

This is an initial "review" of the Lasfit T3 7443. In just 600+ miles, these are the second set of LED turn signals I have installed in this car. So far, they worked as advertised. Though I doubt these are "4000" Lumens. I prefer the design of this bulb over their previous attempt at a "resistor-free" LED. And if Type R owners are using Lasfit, I don't see why my plebian FL2 can't.

If I'm honest, I have a big disdain for Lasfit, stemming back to my 10th gen days. They tend to "buy" influencers by sending free product and make up absurd specs. No matter what, replacement LED bulbs cannot make 13000 lumens. Especially if the headlight or foglight housing is not designed for it.

For that reason, I used bulbs from either Diode Dynamics or VLEDS, or brands used by professional headlight builders. When my FL2 first arrived, I replaced the turn signals with the GTR Lighting i-LEDs that, too, were installed in my FC2.




After a few days, I replaced the reverse lights with VLEDS V6 Tritons, bulbs I used in my FC2 and my old Focus. I tried to do it a the same time as the turn signals, but when following the instructions, the base of the bulb was either too small or, using the included adapter collar, too big to fit in the opening. After some help from VLEDS, I was able to make them work. Coverage and output were amazing and felt as if you had headlights in the rear.

You may be reading the title wondering why I mentioned the above. Well, after four days, the combination of the VLEDS and i-LED caused two fuses on the BCM to pop, and "bricked" my FL2 with 168 miles on the odometer. Thinking this was something else, I limped the car to my nearest Honda dealer, only for them to say the cause of my issue was these bulbs. As a result, I ended paying for a hefty diagnostic fee and was charged $40+ for four incandescent bulbs. Though, after this happened, I noticed the nut holding the positive terminal was loose and at the end of the bolt. I tightend it down and talked to the service manager, who mentioned that one of the techs may have disconnected the battery for a hard reset.

Long-story short, instead beefy bulbs with heat sinks, I just went with direct replacements. The XPRs, while not as bright as the VLEDS, still utilize the reflectors in the housing well. However, since there's a tiny heatsink at the tip of the bulb, there's no light going forward.

I'll update this thread to see if I experience the same failure as last time. And include a night shot of the Lasfit bulbs. Though the XPRs have been in my car for almost a week.

Very strange that the positive terminal was loose. Pretty sure all service instructions would tell the tech to disconnect the negative terminal.

Thanks for sharing your experiences otherwise.

If they performed a battery reset, both terminals would have come off.

As promised, here's a video at night of the Lasfit bulbs in action.


They're much brighter than stock. But, unsurprisingly, not as bright as the i-LED. Please note I left all the video settings on my phone on auto.

I didn't notice for about a week until I decided to look under the hood. Negative terminal was fine. I felt something was off when I blew the horn fuse trying to i stall the Euro horns. I assume the tech failed to tightend down the positive terminal. It's possible I'm not going back to that dealer again in the future.

I have reached out to VLEDS regarding the V6 Tritons. They said the could test my bulbs to see if there were any issues. The 921 base adapters checked out, as did one bulb, with a healthy 0.93 amps. The second bulb failed to power on. I can't be sure if the bulb failing caused too much resistantnce in the circuit. Or if the the bulb failed after the fuses popped.

Update on the XPRs. So far, my FL2 is unscathed. I can confidently say that this combination works on the Civic. However, one bulb has popped off the same socket, twice! For the first occurrence, I bent the metal prongs on the bulb outwards, so it sits snug. That lasted more than a week. The second time, I bent the prongs in the socket inward, in addition to the bulb. Hopefully this is the last time it happens.

Here's a surprising update. After a few months, I have replaced the XPRs with VLEDS High Output 921.

Not because the bulbs failed. But with surprising regularity, the driver's side bulb kept falling out of the socket at least once a month. I was sick and tired of having to fish out the a bulb from the housing. Unlike an incandescent 921, these don't clip into the housing (though I think that applies to all LED 921 replacements). Combined with a heavy base, the bulb slips out over time. I've tried bending the tabs on both the socket and bulb, and applying dielectric grease, as recommended by Diode themselves. But to no avail.

The main reason why I returned to VLEDS is because one of their engineers has the same bulbs in their personal FL5. Plus they have an option for 5000K bulbs, which I went with. Though I haven't measured it, it feels as if the bulb is lighter at the base versus the XPRs. Below is a comparison.

Regarding specs, raw output is 1500 lumens, before stabilizing to 850LM. For comparison, the XPRs have a raw output of 1600 lumens, stabilizing to 720 lumens. It's too early to judge, but when weather permits, I'll update with photos.

Here's a photo of the VLEDS HO 921 in action. There's more dead zones in the light pattern. It's not really a surprise since these are two-sided bulbs versus the four sides of the XPR. But brightness is comparable. I tried to park a similar distance to the outhouse, though I overshot it by a lot.
