Question about Fenix Flashlights Black HL21 Fenix HL21 Headlamp, Black

Can you open the switch end of fenix hl21?

A battery leaked in my fenix hl21 headlamp. Now the light won't turn on. I'm trying to clean the contacts - they're very, very corroded - and it'd be great if I could open the switch end of the battery compartment to do that - is that possible or will I just snap the plastic trying? Many thanks

The plastic will break and even if you do get access to that, the issue with the corrosion will still cause problems.

Right low beam headlight does not come on but my right turn signal will stay even tho i diddnt turn it on. If I cut on my high beams the rurn signal cuts off. Whats wrong? Helo


It could be the lamp control module !
Headlamps
Battery positive voltage (B+) is applied at all times to the lamp control module (LCM) through the underhood fuse block HDLP fuse.
When you place the headlamp switch in the HEAD position, the headlamps input to the LCM is grounded. The LCM then applies battery positive voltage (B+) through the underhood fuse block HDLOBML fuse and HDLOBMR fuse, which feed the left low beam headlamp and the right low beam headlamp respectively. When you activate the headlamp dimmer switch by pulling on the multifunction lever until the switch clicks, the high beam input circuit to the LCM in grounded . The LCM then removes battery positive voltage (B+) from the low beam headlamps and supplies battery positive voltage (B+) through the underhood fuse block HDHIBML fuse and HDHIBMR fuse, which feed the left high beam headlamp and the right high beam headlamp respectively.
Check this fuse in the left under hood fuse box first. HDLOBMR Fuse 18 10 Amp. RH Low Beam Headlamp . If the fuse is good check for B+ voltage with the low beams on . Use a test light or volt meter . If you look on top of fuse there are two metal tabs ,check there for B+ voltage , If no B+ voltage the LCM - lamp control module isn't supplying any .

When my E2d. Ed defender. 200 lumens flash light is turn on it act like an strob light how to stop it or is it a weak batteries


No, that is a 'feature'. It is for signalling or blinding an attacker.

This is the instructions for the 500 lumen version but it will be the same. Nice light, I run Fenix Tactical. Strobe is usually gained by switching on and then half depressing the button and holding. If this doesn't work, contact Surefire direct.

The E2D LED Defender® Ultra is a compact 500-lumen flashlight featuring dual-output capability and self-defense enhancements. Utilizing a virtually indestructible high-performance LED and a Total Internal Reflection (TIR) lens, the E2DL Ultra is activated with a pushbutton tailcap click switch that also selects output levels: press or click once for a high-intensity 500-lumen white-light beam-ten times the light needed to overwhelm the night-adapted vision of an aggressor. Return to off and press or click again within two seconds for a 5-lumen ultra-long runtime low beam that's suitable for navigating at night or performing close-up tasks for hours. The Defender's crenellated Strike Bezel® provides further defensive options should the need arise. Slender and powerful, the E2DL Ultra is an ideal everyday-carry light.

Dim head lamps and day light running lamps won't come on my 2000 Buick lasabre


Daytime Running Lamps
With the daytime running lamps (DRL) programmed to be on, the DRL will operate when the ignition switch is in the ON position, the gear selector lever is out of the PARK position, the headlamp switch is in the OFF or PARK position, and the ambient light sensor indicates daytime conditions. Battery positive voltage (B+) is supplied to the DRL relay coil through the underhood fuse block. Battery positive voltage is supplied through the underhood fuse block FOG/DRL Fuse to the DRL relay normally open contact. The DRL relay normally closed contact receives ground for normal high headlamp operation. When the dash integration module (DIM) determines that conditions are right for the DRL, the DIM grounds the DRL relay coil. This energizes the DRL relay coil and closes the switch to the normally open contact. Battery positive voltage (B+) is supplied to the LH and RH high beam headlamps in series. The high beam headlamps split the voltage and each lights at half intensity. Current will follow the path from the DRL relay to the LH high beam headlamp, HDHIBML Fuse, HDHIBMR Fuse, the RH high beam headlamp, then to ground.
Does your vehicle have
Twilight Sentinel
The twilight delay switch in the headlamp switch is supplied a reference voltage from the instrument panel integration module (IPM). It is supplied a reference ground from the IPM. The switch is a potentiometer that resistance varies as the switch is moved. The IPM receives an input voltage proportional to the resistance of the potentiometer. The IPM sends a class 2 message to the dash integration module (DIM) indicating the on/off status and delay length for the twilight sentinel. With the twilight sentinel in an ON position, the DIM will automatically control the headlamps on/off status depending on the nighttime/daytime status of the ambient light sensor. The DIM will use the twilight sentinel delay length to know how long to keep the headlamps and park lamps on after the ignition switch transitions from ON to OFF during nighttime conditions.
If you don't know about these things you best bet is to take it to an ASE certified repair shop or the dealer .

I have a Fenix TK15 that doesn' light up. I have changed batteries, still no light


Hi marlyn engaling...
Sounds like you need to replace your bulb, it may be burned out.
Also check the switch and also make sure the spring in the back of the flashlight is touching the battery tightly to make good contact.

1999 oldsmobile 88 headlights wont shut off


Pull this circuit breaker till you can find the problem. Check for applicable trouble codes. You have a lighting control module, I can't troubleshoot that component from here.

Fenix hp11 headlight


Hi, I have some experience with this unbekievable good headlight(when it works).
I had a hp10 what started to stop more and more.
After a while it wasn't going on.
5 years warrenty, so i got a new one, the new model.hp11
The main problem is the wire from battery case and the head led.
When there a litte damage inside this wire, light goes of not going on it selfs when it connecting again. After a while it will not work any more.
(if you have a welding station you fix it your self (battery case,can go open by unscrew the wire entrance.)

Chack battery case if the springs are all still connecting the battery.
If you put in one battery false on there is short cut and al sprigs get so hot they will shrink. And stay in that position..fix that your self or ring/ contact the shop you bought it.
There 5 year of garrantie.

The flashlight won't turn on even though it has new batteries.


Check the bulb. Unscrew the light to inspect the contacts for the batteries and (as possible) unscrew in a place you can check the contact points for the bulb, switch and bulb. A simple cleaning with a contact cleaner, WD40, dry wool or as possible a blade (knife).

Headlight problem with my 2000 Corvette. Sometimes when I start the car both headlights pop up and turn on and the switch will not turn them off. I have to turn the engine off and turn the light swith on...


Do you know how to test automotive electrical circuits ?
When the headlamp switch is turned to the HEAD position, battery voltage is applied to the headlamp opening door actuator control module through CKT 103. The LH head lamp door opens when battery voltage is applied to the LH headlamp opening door assembly through CKT 576 and ground is applied to CKT 577. The RH headlamp door opens when battery voltage is applied to the RH headlamp opening door assembly through CKT 578 and ground is applied to CKT 579. When the headlamp switch is moved to the OFF position, battery voltage is applied to the headlamp opening door actuator control module through CKT 306. The LH headlamp door closes when battery voltage is applied to the LH headlamp opening door assembly through CKT 577 and ground is applied to CKT 576. The RH headlamp door closes when battery voltage is applied to the RH headlamp opening door assembly through CKT 579 and ground is applied to CKT 578. Battery voltage is constantly applied to the headlamp opening door actuator control module from the HDLP MOT L MiniFuse® #4 (CKT 2940) and from the HDLP MOT R, MiniFuse #3 (CKT 3040). The headlamp opening door actuator control module is grounded by CKT 150 through Splice Pack #100 to G102.

Headlamp Doors Do Not Close
Install a scan tool and go to the BCM input display.
Monitor the headlamp off switch status.
Turn the headlamps on and off.
